ubuntu software upgrader doesn't start when I click on the icon

[eliyahu22]

I'm using Ubuntu 20.04 LTS, and when I click on the icon for the software updater, he doesn't start. Is there a command for the terminal to start is?

Try

sudo software-center

Or

sudo gnome-software-center

Do you mean the Software Updater app? You can start it from the shell with this command:

update-manager

Analogously, you can also invoke apt like so

apt update

which will first fetch the sources and tell you if there are packages that can be upgraded.

apt list --upgradable

will list those packages. If you're ready, run

apt upgrade

to upgrade them.

apt requires superuser privileges.

Don't forget that you will have to run all the apt commands shown by kbar as root, and will therefore have to use sudo before each command, ie, sudo apt update etc etc.

No. By default, credentials are cached for 15 minutes per terminal. Running it once (in the beginning) is sufficient.

But you still need to use sudo except for the apt list, though you will not need to enter your password again as that is what will be cached.

That's what I've said, yes.

If you run

sudo apt update
sudo apt full-upgrade

Does it work OK?

When I tried this command: update-manager I got the update manager.

It is just that I made a mistake, it is not the software update manager I have problems with, it is the Ubuntu Software icon that doesn't work. That is the square orange icon, which let's you install all kind of programs for Ubuntu. That one doesn't do anything.

Try the following command and report any errors.

gnome-software
