Same, I feel at home in the Cinnamon DE and no matter how tech savvy I am, the GUI software installer is so much more convenient than using the terminal
I have the issue that the snap version can't browse files whose path includes a hidden dot file/directory in my home directory. It doesn't seem there's any clean way for me say "no, I give you explicit permission to read these files." My workaround was to sudo mount --bind ~/.foo ~/bar and then browse from ~/bar instead. I'm not sure what they think they were preventing me from doing but they failed.
Canonical's changes to apt could be considered malicious in and of themselves because it installs from a source you didn't request for, sure seems malicious to me.
