After upgrading to Ubuntu 17.10, Ubuntu Dock icons of some of my apps are not appearing. They appear properly in the dash. I verified the *.desktop files for the applications in /usr/share/applications and ~/.local/share/applications.  E.g. dock icon is not displaying for "Terminator". Check out the attached image.    This is how the icon for the same application appears in dash search:    Content of /usr/share/applications/terminator.desktop:  [Desktop Entry] Name=Terminator Comment=Multiple terminals in one window TryExec=terminator Exec=terminator Icon=terminator Type=Application Categories=GNOME;GTK;Utility;TerminalEmulator;System; StartupNotify=true X-Ubuntu-Gettext-Domain=terminator X-Ayatana-Desktop-Shortcuts=NewWindow; Keywords=terminal;shell;prompt;command;commandline; [NewWindow Shortcut Group] Name=Open a New Window Exec=terminator TargetEnvironment=Unity   Any pointers to debug this issue will be helpful.

I havent used my Ubuntu for quite a long time.  Today, when I booted Ubuntu (14.04 LTS), the software updater and Software &amp; Updates (from Settings) are not working.  The software updater's window will show up for around 1 sec, but it will close automatically. Software &amp; Updates is never shown, no matter how many times I click the icon. Note that neither of them show any error message.  Those 2 features were working perfectly the last time I used Ubuntu. I want to do some system upgrade and update.  For now, I use sudo apt-get update &amp;&amp; sudo apt-get upgrade. This command runs very fast, meaning (I think) my Ubuntu is not updated properly. The update from software updater always has a big size hence the download should be slower.  What should I do?   Can I just uninstall and reinstall both of them? If I can, how to do it?  Just to clarify, I don't want to upgrade my Ubuntu version (I want the LTS one), I just want to upgrade the software/packages I used.  Thanks for your time.

While I was upgrading to Ubuntu 15 (the development version), my system crashed. After I restarted the laptop, I saw a kernel panic. I also did a memtestx86 which didn't find any error.    more info :   Before doing upgrade i have changed my default desktop to gnome which by entering wrong commands i lost some packages .to revert the previous desktop i removed all the packages and then installed them then i face that some packages weren't still installed . after i run terminal and started to upgrade ( i found it good to troubleshot the problem by upgrading somehow ) however after crash i got that screen by the way i have faced another screen after this one which backed to the first again

I am not looking for a workaround or a hack.  I am just confused.  14.04.1 has been released now for a week, and one of my machines which is on 12.04, and another one which is on 14.04 both don't have the upgrade options.  I see there is a 14.04.5 release on august 7th but I am not sure what a candence event is.    It is hard to believe that it is not an issue that is going to be resolved otherwise I would hope this would be posted on the Ubuntu blog.  I cant be the only one on the last LTS waiting for it to update so I can finally go to the latest kernel and properly use my core i7 graphics.

I tried to upgrade from Ubuntu 16.04 to Ubuntu 18.04. First, after downloading and installing of packages, I was unable to login. Login screen hanged completely and it showed Failed to authenticate. But then I logged into tty1 and then logged in Ubuntu. It was saying that I am in Ubuntu 18.04. Then it asked for reboot. So I rebooted Ubuntu from terminal. It got stuck at something like /dev/sda4 : Cleaning files. After trying for a few times, I got into tty1 and here I logged in as root user and tried to update and upgrade. But now I am getting errors like unmet dependencies and broken packages. I have done sudo dpkg -- configure -a. I don't want to do a reinstall of Ubuntu. How do I get access to my Ubuntu Desktop?

Is there a way to install GNOME extensions from terminal, for example dash to dock? The way I do it now is to go into Ubuntu Software app store and install it.

I completely erased the old disk data and installed the 20.04 LTS version of Ubuntu but the Ubuntu software on the dock doesn't start. Then I ran in the terminal:  sudo apt install --reinstall ubuntu-software   It went fine. But still it doesn't open. Then I searched in dash for "software" and found two software center. One named Software and other Ubuntu Software. Software starts but Ubuntu Software doesn't start. In the dock there is Ubuntu Software which doesn't start.    Another thing, Running sudo apt update says All packages are up to date but in the Software it shows 2 updates needed. This is strange.    Why there are two software centers? One of them starts and the other doesn't. The one which starts shows pending updates but in terminal there is no pending updates.  Update: According to first answer I ran snap-store form terminal and got this:  16:30:11:0219 Gtk Failed to load module "canberra-gtk-module" 16:30:11:0225 Gtk Failed to load module "canberra-gtk-module" 16:30:14:0571 Gs  plugin appstream took 3.0 seconds to do setup 16:30:14:0580 Gs  enabled plugins: desktop-categories, fwupd, os-release, packagekit, packagekit-local, packagekit-offline, packagekit-proxy, packagekit-refine-repos, packagekit-refresh, packagekit-upgrade, packagekit-url-to-app, appstream, desktop-menu-path, hardcoded-blacklist, hardcoded-popular, modalias, odrs, packagekit-refine, rewrite-resource, packagekit-history, provenance, snap, systemd-updates, generic-updates, provenance-license, icons, key-colors, key-colors-metadata 16:30:14:0581 Gs  disabled plugins: dpkg, dummy, fedora-langpacks, fedora-pkgdb-collections, repos 16:30:16:0144 Gs  /etc/PackageKit/Vendor.conf file not found 16:30:17:0235 Gtk Could not load a pixbuf from icon theme.

I recently installed Ubuntu 18.04 and I'm not keen on the desktop environment. I want the desktop env. I used to have in Ubuntu 14.04. How can I get it?  I've attempted to use , but when I try to install the Unity's 7.2.5 version using the command:  apt install unity=7.2.5   it gives me   E: Version '7.2.5' for 'unity' was not found   For sure I need to add a PPA for this, but which one!?

About 10 minutes ago I set up my basic Terminal app to be semi-transparent and was really happy with the result. Now, some updates ran and the whole "Background" tab is gone from Terminal settings. Was this option removed? If yes, why? Why would anyone do that?  I'm running gnome-terminal 3.10.2 from the Gnome3 ppa.

I just finished installing Ubuntu 14.04 and Gnome Shell sudo apt-get install gnome-shell ubuntu-gnome-desktop, however when I checked what version has been installed I read 3.9.90: is this correct?   Isn't Ubuntu 14.04 supposed to ship with gnome 3.10 at least? What am I missing?

I have a laptop with Ubuntu 17.04 desktop installed. And I noticed that Ubuntu has just announced their new version (17.10). However, when I'm trying to open update-manager, it just tells me that I have the newest version.  Also, when I type the sudo do-release-upgrade command on the terminal, it tells me the same thing (No new release found.)  Is there any reasons for that, and what can I do? or should I just wait for that version, to get to the server?

I just installed Ubuntu 18 on my desktop PC alongside Windows 10 and have been using Ubuntu without any problems for a couple of days. Today, when I booted up my computer, I am no longer able to open the terminal at all. I've tried restarting it multiple times, but it still won't work. If I click the terminal icon on my task bar, nothing happens. If I try opening the terminal with CTRL+ALT+t, it still doesn't work.   How can I resolve this?

^^^^ Will Ubuntu GNOME upgrade to Ubuntu 18.04, or will support discontinue when 18.04 is released?? Just want to know what's better to run right now so I can upgrade and not have to reinstall later(I intend to see this transition through)-- GNOME installed correctly on vanilla Ubuntu, or Ubuntu GNOME?
