I just installed the Gnome Desktop on the freedombox. It works. But then I wanted to install an app to it and figured out, my admin account, which I logged into the Gnome Desktop with (the account with full permissions you create as the first user) is not sudo on this gnome Desktop.
Instead Gnome prompted me with a passwordbox for the “fbx” user. In the plinth user menu, there is no user “fbx”
Gnome says, that the user fbx is admin but the account is disabled
Being able to use the “sudo” command from a user (can be done by adding configuration in /etc/sudoers) is not the same as the user account being part of the “sudo” group (in /etc/group). So, the solution will likely work.
