No app can be installed in my system after I recently upgraded from Ubuntu 19.10 to 20.04.

$ sudo apt-get install vlc gimp gparted synaptic

Package synaptic 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

E: Package 'vlc' has no installation candidate


E: Package 'gimp' has no installation candidate

How can I fix this issue?

Did you updated your ubuntu from 19.1 to 20.04 or did you do a fresh install?

Also, try this: Error when install with apt-get install

It says that you should have universe repository

sudo add-apt-repository universe

Then run

sudo apt-get update

and if you have an installed system (but not if you have a live or persistent live system)

sudo apt-get dist-upgrade
