I installed SimpleScreenRecorder with command:  $ sudo snap install simplescreenrecorder   I then tried to configure a record session so that the output would be saved on a USB drive, but as soon as I try and access the /media folder for the Save As path, I get the following error:   Having experienced the same issue with GIMP in an earlier post, I tried the following command (which worked for GIMP) to solve the problem:  $ sudo snap connect simplescreenrecorder:removable-media   However, that resulted in the following error message:  error: snap "simplescreenrecorder" has no plug named "removable-media"   Is it possible to have SimpleScreenRecorder output to removable media, or is there a technical barrier preventing this?  Update: I find that SimpleScreenRecorder is now available to install from apt directly. So I removed the snap version:  sudo snap remove simplescreenrecorder   Then installed from apt:  sudo apt install simplescreenrecorder   The trust and permissions that come with being a core apt package means the application has access to removable media without further configuration.

I have Ubuntu 18.04 LTS installed. I inserted USB-flash to my laptop. It was automounted to /media/username/DISKLABEL and opened in Nautilus. I can read and write objects to it. How can I access it from the application, which is installed as Snap? I tried snaps of the following applications such as gedit, arduino-mhall119, organize-my-files. All them show me errors if I navigate to /media folder:    Could not read the contents of Media Error opening the directory of '/media': permission denied  Output of active Snap  is below: $ snap interfaces  | grep -v &quot;.*-$&quot; Slot                             Plug :browser-support                 organize-my-files :core-support                    core:core-support-plug :cups-control                    gedit :desktop                         gedit,organize-my-files :desktop-legacy                  gedit,organize-my-files :gsettings                       gedit,organize-my-files :home                            arduino-mhall119,gedit,organize-my-files :network                         arduino-mhall119,gedit,organize-my-files,pulsemixer :opengl                          organize-my-files :pulseaudio                      organize-my-files,pulsemixer :unity7                          arduino-mhall119,gedit,organize-my-files :wayland                         gedit :x11                             arduino-mhall119,organize-my-files,pulsemixer gnome-3-26-1604:gnome-3-26-1604  gedit gtk-common-themes:gtk3-themes    gedit gtk-common-themes:icon-themes    gedit gtk-common-themes:sound-themes   gedit -                                arduino-mhall119:serial-port -                                gedit:avahi-observe -                                gedit:mount-observe  Updates:  connecting mount-observe to Gedit with snap connect gedit:mount-observe does not help. it seems that we need special Snap with support of  interface.

I just realized using gnome-disk-utility (3.18.3.1) that my 16.04 installation is featuring several small loop devices.  In detail:   78 MB Loop Device (/var/lib/snapd/sn_ntu-core_352.snap -> /dev/loop0) 76 MB Loop Device (/var/lib/snapd/sn_ntu-core_216.snap -> /dev/loop1) 79 MB Loop Device (/var/lib/snapd/sn_ntu-core_423.snap -> /dev/loop2) 705 KB Loop Device (/var/lib/snapd/snaps/tpad_12.snap -> /dev/loop3) 684 KB Loop Device (/var/lib/snapd/snaps/tpad_11.snap -> /dev/loop5) 705 KB Loop Device (/var/lib/snapd/snaps/tpad_13.snap -> /dev/loop6)   Image showing gnome-disk-utility    My questions are as follows:   What are those loop devices used for? Is that an expected behaviour in 16.04? Can  I remove them? And if so - how (just by unmounting)? Is there any risk in removing the 2 installed snaps mentioned below (tpad and ubuntu-core)   UPDATE  Installed snaps  According to snap list I do have   tpad (1.8.1) ubuntu-core (16.04.1)   installed. I remember I did tinker with snaps for a short time when  I realized this option - but am pretty unsure if  I  installed those 2 snaps - or if they are pre-/auto-installed.  tpad is a Terminal text editor with GUI-like user interface  I  did install manually, as  I don't use it  I removed it now via sudo snap remove tpad. As a result the 2 loop devices pointing to tpad are gone in gnome-disk-utility.  So - at the current point  I am still having 1 snap installed called ubuntu-core and I don't know what it is used for. The summary of this particular snap is   The ubuntu-core OS snap

Is there a command line utility that allows me to take a picture from the built in camera?  Something like screencapture allows for, well, screen captures.  The reasoning for a command line tool is I would like for it to be stealthy, without a countdown or flash or other indication to the user that a picture is being taken.

I have just compiled my own copy of ffmpeg on my system and it's located in the following path:  /opt/local/bin/ffmpeg   When I run the following command in Terminal.app, it runs smooth:  ffmpeg -i /Users/Amit/Documents/input.avi -c:v copy -c:a aac -b:a 384k -strict -2 /Users/Amit/Documents/output.m4v   However, a similar command run as a shell-script in an Automator service fails:  for f in "$@" do     ffmpeg -i "$f" -c:v copy -c:a aac -b:a 384k -strict -2 "${f%.*}.m4v" done   Up until now, I had a pre-compiled build of ffmpeg on my system located at:  /Applications/Scriptlets/   And my Automator shell-script had the full path (/Applications/Scriptlets/ffmpeg) instead of just ffmpeg; and it worked fine. However, today I decided to compile a fresh copy of ffmpeg using MacPorts and removed the earlier version from my Applications/Scriptlets folder. Now, this ffmpeg works fine in Terminal but gives an error whenever I try running it from a shell-script inside of an Automator workflow. Am I doing something wrong here? Please help!

I am running Lubuntu desktop 12 and I am looking for a tool that can take screenshots of a certain area from the command line.   I have tried out Shutter. It works but, when I run the command  it generates warnings ( Wnck-WARNING **: Unhandled action type). I think the tool might be designed to run under GNOME and might not be compatible with Lubuntu. The screenshot is taken successfully, but the command hangs, which is something I cannot work with.  So what is a good screenshot tool that    Runs from the command line Can capture a certain area of the desktop     I like to add that scrot, the tool Lubuntu ships with, does not have the option to crop certain coordinates, but only an interactively user-defined area which is not what I'm looking for.

What's the difference between the snap folder in /home/&lt;UserName&gt; and the snap folder in root (/)?  I'm trying to get a grasp on where programs and their files are stored when you install them.  The first and only program I have installed on my machine is Spotify.    I noticed that there were two spotify folders within two separate snap folders.  One in the home directory and one in the root directory.    Questions   Why are there two snap folders? Why are there two spotify folders? Are they different in any way (the snap and spotify folders)?     NOTE: I installed Spotify via the Ubuntu Software application, not via the Terminal.

I have installed chromium snap package. Each time I download file and try to open it or download folder I see a GNOME prompt form with question:      Allow opening file?   Allow snap "chromium" to open file "/home/username/Download"?   How can I disable it permanently? Is there an option to grant read/open permission to this folder for particular snap package?    OS: Ubuntu 18.04 LTS X: GNOME snapd version: 2.33

I have installed KeePassXC snap package on Ubuntu 17.10. I have multiple linux systems installed on the same drive, so I have made most of my home folders like ~/Documents created as links to a separate ext4 partition (users have same uid so permissions are correct). I tried to open my passwords' database which I have inside Documents, but keepassxc cannot see any files inside Documents. If I put the file in my home folder then it sees it.  Are snap packages able to find files outside from my home folder? Any way to make KeePassXC (and the rest snap packages) access the files at my separate ext4 partition (maybe some configuration somewhere)?

I'm not particularly fond of apps cluttering my $HOME directory with their own files or directories. It's rarely a problem, because most apps have the courtesy to hide their data by prefixing it with a dot or conforming to the ~/.config standard. But not snap.  Q1: Have I misunderstood this directory?  Is ~/snap really a directory which I'm supposed to enter and access on a daily basis on a par with ~/downloads, ~/pictures, ~/work, etc?  Q2: In any case: Can I move it e.g. ~/.snap?  I can't find anything like /etc/snap, /etc/default/snap, or ~/.config/snap to tweak things. I tried export SNAP_USER_DATA=$HOME/.snap but it didn't work.

First the caveat: I understand that this question involves Mate and a Raspberry Pi so if you consider it outside the realm of this forum just ignore it.  But on the chance that it may be helpful or typical of something involving snaps or that platform, here goes.  I decided to try and install the nextcloud snap. It threw a ton of errors and seemed to freeze in the middle of the process (for over an hour). I killed it and just decided to try and remove it. The install looked like....      $ sudo snap install nextcloud 2016-06-24T08:48:29-04:00 ERROR cannot setup apparmor for snap "nextcloud": cannot load apparmor profile "snap.nextcloud.apache": cannot load apparmor profile: exit status 1 apparmor_parser output: Cache read/write disabled: interface file missing.

[|] Setup snap "nextcloud" security profiles   When I try snap remove nextcloud I get         error: cannot remove "nextcloud": snap "nextcloud" has changes in progress   What I would primarily like to do is properly remove the snap and recover the space from the partition it created.

At some point something seems to have completed in the background because lsblk shows nothing and the snap interfaces query shows nothing.

I want to change the default location of "Save a screenshot to Pictures" to save it to Desktop.   If that is not possible, is there any other way to do it? I am using Ubuntu GNOME 17.04.  NOTE: I don't want to change the location with dconf-editor as it changes the location of screenshot applet and not of the shortcut I require.

How can I record my screen on Ubuntu?   The app I'm looking for has ideally all of these features:   Can record in a format that can be played back easily on any platform and/or accepted by YouTube or another popular video site Can record just a window (instead of the whole screen), possibly selecting it with a mouse click Can start recording after a configurable delay (e.g., I launch the app and have time to do arrangements to my desktop/window before actual recording starts)

This question is NOT about access to USB or external drives.  WPS Witer and other just installed Ubuntu software can NOT open files saved on my /media directory. I keep getting the annoying message: « Could not read the contents of '/media': Permission denied ».   MY SIMPLE QUESTION REMAINS:  How can I access all files and folders on my user username/media/ directory?  I'm using Ubuntu 18.04.3 LTS.  Ubuntu's Nautilus can indeed access all files and folders in all locations. However, Ubuntu's software that I have downloaded (e.g. KRITA, WPS WRITER etc) can NOT access any file or folder on the /media directory. Thanks in advance.

I didn't see any hits about this on google, so I'm asking you:  I just tried to run this command in an ssh session, local is Debian Wheezy KDE, remote is Fedora 21 Gnome:  ps aux | grep xscreensaver   and this is the output:  bash:  grep: command not found...   I never seen this before, what is the cause?  I just few hours before updated the system, but didn't see any packages marked for removal. There are only two users on the system, and only me installs or removes software on it.  EDIT #1  Here is the commands and output copied,notice that the space is not there the second time:  [root@Hostname ~]# ps aux |  grep xscreensaver bash:  : command not found... [root@Hostname ~]# ps aux | grep xscreensaver bash:  grep: command not found...

I have a Canon Pixma P200 and I have downloaded the Linux drivers from their site. I extracted them and I found 4 .rpm files. I decided to open terminal and type in  /home/rsbayani/Desktop/cnijfilter-p200series-4.00-1-rpm/packages/cnijfilter-p200series-4.00-1.x86_64.rpm -i   but it doesn't work, it just gives me permission denied. I also tried the code below  /home/rsbayani/Desktop/cnijfilter-p200series-4.00-1-rpm/packages/cnijfilter-p200series-4.00-1.x86_64.rpm --install   But like the one above it, it ssill gives me a permission denied. I am using Ubuntu 14.04 LTS. Any help would be gladly appreciated.

I seem to be having issues when I try and save the output file as a .png, or .jpeg for that matter. I've set up my user preferences, File, Render Output to my desktop as well as render output in the editor window. What am I missing here? I'm obviously very new to this program and your help would be appreciated. Thanks for your time
