Ubuntu software cannot install some programs

Question

I installed Ubuntu 20.04 LTS and when I open Ubuntu Software and click to install a program, it gives me this error:

(Visual Studio Code is an example.)

this happens to the programs like mc-installer (minecraft installer) too. but always this command will install the program:

sudo snap install program-name

But sometimes I don't know the name of a program in command line. Something like Visual Studio Code. The next problem is: Ubuntu Software doesn't tell me the error! After the "cannot perform the following tasks:: is the end of the alert!

But sometimes graphical way can install some programs, such as VLC Media Player.

How can I do to fix the error of ubuntu software?

Answer 1

For example, VSCode has the snap package name code. But when using apt or apt-get some programs may be for older Ubuntu versions, but still show up because they are in the repositories.
