SUMMARY A user on Kubuntu 22.04 with standard privileges cannot use the computer after a reboot, since he gets two dialogs: one to enter the password for wifi and second to select an admin user and enter the password to mount the SSD disk. This discourages other users in my family to use Kubuntu/KDE, instead they boot into Windows where this simply works for them. STEPS TO REPRODUCE 1. Install Kubuntu 22.04 on a regular laptop with an SSD. An admin account is created during install. 2. Logon, connect to a wifi network, and select “All users may connect to this network”. 3. In Users add a user with standard account type. 4. Switch-user to this standard user. Everything works fine, no nagging dialogs. 5. Reboot and login with this standard user. OBSERVED RESULT The two annoying dialogs are shown as described in the summary. As a result a standard user is not able to use Kubuntu/KDE after a reboot. EXPECTED RESULT That a standard user is able to use Kubuntu/KDE after a reboot, like on Windows.
You shouldn't need to be an admin user to do these things. The wifi issue can be fixed by storing the wifi password for all users rather than on a per-user basis in System Settings > Connections > [the wifi network in question] > "Wi-Fi Security" tab. The password to mount SSD issue is a Kubuntu problem; it's possible to make this action not require authentication, but that's up to the distro to do, not KDE.
