1) Setting up Wi-Fi prompts KDE Wallet for a wallet type, the default option, GPG encryption, doesn't work unless someone generates a key via terminal, so you have to select "blowfish".
4) No clear way of installing ubuntu-restricted-extras from Discover
6) after restarting the system, kde wallet prompts for login despite sddm auto logging in
if you use auto login, you don't care about security, so don't bother prompting to login to the wallet
5) apt autoremove isn't run when doing updates
all those packages that won't be removed...
