I cannot install any meeting software in Ubuntu 21.04.

I have tried-

  • Zoom
  • Cisco Webex Meetings

Whenever I try to install any of these, I am shown that I have unmet dependencies.

I have also tried installing Zoom with gdebi, but it did not work as well.

If I run-

sudo gdebi Downloads/zoom_amd64.deb

I get-

Reading package lists... Done

Building dependency tree... Done

Reading state information... Done

Reading state information... Done

This package is uninstallable

Dependency is not satisfiable: libgl1-mesa-glx

So, when I try to install it-

sudo apt install libgl1-mesa-glx

I get-

Reading package lists... Done

Building dependency tree... Done

Reading state information... Done

Package libgl1-mesa-glx is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

When I try to install Webex in the same way, same problem-

This package is uninstallable

Dependency is not satisfiable: libgl1-mesa-glx

Here's what the apt GUI installer shows-

I have reached an impasse. How do I deal with this?

    Try with apt-get instead of apt. Commands --> sudo apt-get install libgl1-mesa-glx. If this does not work, run sudo apt autoremove && sudo apt update. I don`t remember, but one of them worked for me.

    Maybe you're missing some of the repositories. if @Master_Nachi solution didn't work please post the result of cat /etc/apt/sources.list

You seem to be missing the main repository. To add it simply run the following commands:

sudo add-apt-repository main
sudo apt update

after that you should be able to install libgl1-mesa-glx

  • That totally worked. Thanks. I have never seen this happen. Any idea why this happened?

  • @swift_truth Maybe you have accidentally disabled it from Software & Updates? Nothing else come into my mind.
