Same problem, different ppa

That should give you the answers you need, just change the ppa in the answer to the repo that your error produces.

yaaaaaaa. just checking. feels like time to move onto arch or … gulp… Gentoo.

Is there a way that i can atleast update the rest of the software

Relying on PPA’s or any “external” repos falls on the user. If you move to arch, you’ll be responsible for managing your use of AUR packages, and fix it when it breaks, and the same goes for Gentoo overlays. I was an arch user for 8 years and moved to gentoo for stability and no systemd. If you want to move for the sake of want moving, that’s up to you, but I want you to know that you’ll have to solve these sorts of problems no matter the distro. That being said, Arch and Gentoo are not as hard as people make it out to be, especially if you are willing to ask questions in the IRC.

I guess the point is once gnome was absorbed in the ubuntu world, they stopped do releases, forcing users to eat the canonical version

Fair enough. I assume that you are not wanting to give up gnome which is the reason for the switch. Both Arch and Gentoo (I’ll also include Void) are good distros of user choice as long as you are willing to put in the work. Fair warning on Gentoo if you stick to gnome. Gnome is REALLY dependency heavy, so you are in for a big compile, so I hope you have the hardware or time to handle if you come to the dark side. I personally use sway (on wayland) and it’s a pretty light system even for my laptop to compile. Chromium is currently 2.5 hours in a compile right now running on 12 threads, and still going on my Ryzen 7 1700 (3.8GHz). It’s worth it for me personally though, but thought I’d mention. We are now off topic, so before this gets locked for derailing, either post again with a thread for this discussion, or DM me. Glad your problem is “solved” at least.

Why can a standard user account roam the home folder of an admin?

That comes down to permissions. The default permissions of a homedir are 644 for files, and 755. Refrence https://chmod-calculator.com/

Owner can read/write (directory needs execute bit to enter into them, which is why the are 1 number higher).

Example.

Owner Group Else
6         4         4
rw-       r--        r--

In that standard example everyone can read, owner can write. You can change the permissions to 640 if users aren’t in the right group, they can’t read. You can find permissions, who owns files, and what group they belong to with ls -al and example on my system would be

Permissions   User   group       date/time    file
drwxr-xr-x  8 kdb424 kdb424 4096 Jan 10 19:37 discord

That’s equivalent to 755 if you check the calculator. I’ve only labeled the important parts for this discussion.
