Could you add a journalctl -b 0 log from a session when you did those actions? Also what happens if you try to snap install a snap from the commandline?

What does happen: I'm logging in with an LDAP user. This user does not have sudo access. When I select software from gnome-software ("Ubuntu Software"), it pops up and asks for my users password. I enter this in, and the software then installs (tested with blender, libreoffice, opencl driver). My user does *not* have sudo access on the system. $ sudo su - [sudo] password for jason: jason is not in the sudoers file. This incident will be reported. It appears these *may* be being installed with Snaps ... which still: How, without having root access, can an unprivileged user install something onto the system?
