ubuntu-support-status: command not found
2310 packages installed, of which:
1850 receive package updates with LTS until 4/2025
 330 could receive security updates with ESM Apps until 4/2030
  13 packages are from third parties
 117 packages are no longer available for download

Packages from third parties are not provided by the official Ubuntu
archive, for example packages from Personal Package Archives in
Launchpad.
For more information on the packages, run 'ubuntu-security-status
--thirdparty'.

Packages that are not available for download may be left over from a
previous release of Ubuntu, may have been installed directly from a
.deb file, or are from a source which has been disabled.
For more information on the packages, run 'ubuntu-security-status
--unavailable'.

Enable Extended Security Maintenance (ESM Apps) to get 0 security
updates (so far) and enable coverage of 330 packages.

Enable ESM Apps with: ua enable esm-apps

Why not just run:

sudo vim /etc/apt/sources.list

instead of 2 steps, it can be one.....Makes more sense.

If you are asking how to enable the proposed source, you probably shouldn't use the proposed sources. They aren't for the average user.

Manfred Hampl (m-hampl) said : #5

The program that you are looking for is named

ubuntu-software

What happens when you search for that program after clicking in the nine dots in the bottom left corner of the screen?

And you should not enable, but disable focal-proposed.

Manfred Hampl (m-hampl) said : #6

Sorry, I missed to see that you are running Ubuntu focal: in focal the name again is

gnome-software

just search for that program in the dash, or open a terminal window and issue that command.

the GNOME SOFTWARE icon should be something like the above picture. BUt it
comes as bellow.

Replying to the e-mail notification with images does not work.
You have to upload the images to some kind of public image hosting service and post links.

Can you help with this problem?
