Please let me know how to install Adobe Flash Player on Ubuntu 18.04 LTS from command prompt. I tried enabling Canonical Partners repository using the following command without any success:  sudo add-apt-repository "deb http://archive.canonical.com/$(lsb_release -sc) partner"   Here is the error message:  E: Malformed entry 53 in list file /etc/apt/sources.list (Component) E: The list of sources could not be read.

I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that.  I just tried to upload a screen shot but since I'm new it won't allow me to.  I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following:  COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse)  E: The list of sources could not be read.,  E: The package list of status file could not be parsed or opened.   How do I report bugs?  What can be done about this.  I have searched and everything everyone says to do leads me back to the same line error message.  So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software.

When I go to websites using Flash in Firefox, I get this warning:     This plugin is vulnerable and it should be updated.   Mozilla's  agrees:     Adobe Flash Player Shockwave Flash 11.2 r202 vulnerable 11.2.202.438   But if I follow the update link and download the Ubuntu version (opening with Software Center) I get     There isn’t a software package called “adobe-flashplugin” in your current software sources.   If I run  sudo apt-get update sudo apt-get install -y flashplugin-installer   I'm told     flashplugin-installer is already the newest version.   So how can I update?

Google has  so on a 32bit Debian machine it's not possible anymore to update the APT repository:  W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)   Also has the .deb file removed from Google servers as it seems.  Is there any alternative .deb download of the last release (46?) available somewhere?  Reason: For an automated Debian build system (debootstrap-based) I urgently need a way to install Google Chrome 32bit v46 (or similar). Switching to another browser (including Chromium) is not a quick enough option for me at the moment..

Since Adobe recently dropped support for Firefox on Linux, I can't get flash player to work properly on Adobe Connect in Ubuntu. YouTube videos work fine, I only have problems with Adobe Connect.  I am using Ubuntu 12.10 and Firefox 18.0.1 and Flash 11.2.202.261.  Is there a PPA or another lead I could use to get the latest (or more current) version of Flash Player for Ubuntu?

I know the thread  However, there is no Linux anymore in the installation site .  Unsuccessful attempts   I do DriraWassim's proposal which does not add anything to apt-get and does not show the installed .deb package in the path/search  sudo apt-get install libxml2:i386  sudo apt-get update sudo apt-get upgrade  apt-cache search adobereader-enu   I download the newest .deb package  and run it.  I cannot find the application anywhere in the system. It is not in the path and not in Ubuntu's search. How can you start it?

I installed Ubuntu 16 desktop a few weeks ago. Added Chrome and all fine. However now when I try sudo apt-get install ffmpeg, I get this error message:  Reading package lists... Done Building dependency tree        Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies:  google-chrome-stable : Depends: libappindicator1 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).   What's the problem and what should I do?

I have installed Debian on my pc, but the problem is that at the moment I have no Internet connection to this pc. So, to install a program I have to manually downloaded from a pc with internet and then install it to the linux-debian computer.  The question is this: Is there a standard way to make the installation manually? Note that when I connect a usb flash with the program I want to install(that is:   cdparanoia_3.10.2+debian-10.1_i386.deb) and I try opening it I get the message:     Failed to execute child process “ar” no file or directory.

I think this issue has been going on for over a month now.  I boot my PC and the Adobe Updater tells me to download a new version of Flash. It sends me to  with the following information visible:     Version 11.9.900.152      Your system:      Windows, English   The Update Now button simply links to      I've cleared my cache, that didn't help. The Are you an IT manager or OEM links me to a page where I can either Apply to distribute Flash Player or Download Adobe Flash Player, the latter just sends me back to where I came from. I've uninstalled and rebooted, went to the Adobe website and clicked Adobe Flash Player under the Download menu. The Install now button again links me to  Need Flash Player for a different computer? sends me to  and the Download now button is greyed out and unclickable.   How can I update?

According to this  I should be able to install the .deb version of the Unity Editor for Ubuntu. I have the recommended system requirements. But when I try to install the .deb file using the sudo dpkg -i mydebfile.deb I get the following errors:  Selecting previously unselected package unity-editor. (Reading database ... 175283 files and directories currently installed.) Preparing to unpack unity-editor-5.3.4f1 20160503_amd64.deb ...

EDIT: I've been asked if the question  has solved my problem. The answer is: No, it hasn't. The answers in that question might help one learn how to fix broken dependencies using sudo apt-get -f install but that didn't solve my problem. I had to install each of the missing packages one by one (see comments below). So, I think people coming here for the same problem won't be able to know that they have to install the packages by hand if the question is marked as a duplicate.

Is there a Ubuntu compatible version of the "Adobe Shockwave Player?" I'm running Firefox and when I try to bring up one of my School's websites it says missing plugin. When I click on "Install missing plug-in" it says none found, so when I click on manually install plug-in it takes me to Adobe Shockwave Player installation, but there is no ubuntu version to install??? On the Firefox plug-in finder service it says "Unknown Plugin (application/x-director)
