Ubuntu: Can't install software from the Snap store

,
#21

Oh man, I can't believe you reinstalled for something that was fixable! I wish I'd seen this thread last month... :unamused:

Alas, there's two similarly named groups: adm and admin. You should have added yourself to the admin group and then logged out. adm is for internal use only! Do not add yourself to that group!

(Yes, I know it's messed up that there's two similarly named groups on the same system. I used to get confused.)

Confirm what I said by running groups under your reinstalled system. You should see an instance of admin, and probably not an instance of adm.

In Ubuntu, we don't have admin but sudo.

OP's account was the only one (as stated) so he would already be in the sudo group (that's default); it was not necessary to add again to sudo group. From what I read and understood, there was no issue but only a misunderstanding about how sudo works. Comments #14 and #18 have explained clearly.

On freshly rebuilded UM 20.04 caused by motherboard + CPU upgrade :

Wow! Seriously?

Well, I guess there must be something wrong with my installation.

#25

Maybe, maybe not. I show the same as olek on my 20.04.2 system for what it's worth.
