Problem Description:
The “Software Sources” app in the main menu under Preferences → Software Sources doesn’t work on 26.04 LTS, the shortcut points to “-E software-properties-qt”, but if the “-E” is removed then it works.
Software sources not working is not a bug. Canonical removed GUI access to software sources. You can still access it via command line but apparently canonical doesn’t want the beginner/average user messing with repositories. Whats interesting is you can go to the snap store (or in this case for lubuntu (discover)) and install a 3rd party app that will work similar but doesn’t that defeat the purpose? I think canonical is overreaching with 26.04 and combine that with other decisions they made is going to push me elsewhere going forward. https://www.makeuseof.com/ubuntu-2604-replacing-classic-tools-i-actually-prefer-the-new-ones/
OP’s issues has nothing to do with the removed GUI and Canonical’s reasoning for doing so are very sound, as always:
Plus, OP is using Lubuntu, so shouldn’t even notice that particular change.
What’s even more interesting, is, that “Software & Updates” can still be installed from plain old Ubuntu sources :
sudo apt install software-properties-gtk
I think you have some kind of latent hostility towards Canonical, probably borne from some “bad press” from some shady actors on the Internet. These changes are all in the name of the best possible UX, especially for total novice users. It has been said more than once that Ubuntu is akin to MacOS in the Linux world:
Do watch that video to the end, if you don’t believe the MacOS quote. I can go as far back as Ubuntu Unity which first gave me a real sense of a MacOS experience, only better. But “the internet” didn’t like it, so it had to die.
Yes, it still hurts. And no, the Unity flavor alone won’t cut it for me.
Thanks for the replies, and yes, you can run it via command line (sudo software-properties-qt), whatever the case if the distribution (Lubuntu, Ubuntu, etc) or if it is Caninical’s decision then it should be removed from the menu since it could cause confusion and mistaking a “feature” from a bug.
But you don’t have to. My comment was about sudo apt install software-properties-gtk, which will simply bring it back; from then on it will be available in the menu; the point being that Canonical are not taking anything from anyone; it’s in the Debian archives from which Ubuntu is made, after all. Release upgrades shouldn’t remove it from existing installations and new users shouldn’t even know it ever existed. This is just Canonical putting some under lock and key; the key being in the users’ hands all the time, they just need to know where to look.
