I've been impacted by this issue as well after upgrading from 24.10. I've tried to disable the apparmor profile for remmina but was then greeted with an error message indicating it fails to query the profile from AppArmor.
$ sudo aa-disable remmina Disabling /etc/apparmor.d/remmina $ remmina remmina-Message: 12:18:32.340: Remmina does not log all output statements. Turn on more verbose output by using "G_MESSAGES_DEBUG=remmina" as an environment variable.
