The bug report you mentioned is about a thunderbird profile which is not directly placed in /home/$username/.thunderbird which AppArmor can't get handled correctly without further tuning. ... > Kernel: Linux 4.19.0-5-amd64 (SMP w/4 CPU cores) > Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, > TAINT_UNSIGNED_MODULE > Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE= > (charmap=UTF-8) > Shell: /bin/sh linked to /bin/dash > Init: systemd (via /run/systemd/system) > LSM: AppArmor: enabled You have installed and enabled the apparmor package, I'm quite sure you also have a enabled AppArmor profile for Thunderbird. The thunderbird package isn't installed with a enabled AA profile by default. Please check for some log entries in /v/l/messages about denied access. Append such log entries to this report. https://wiki.debian.org/AppArmor/Reportbug#Provide_logs_and_inspect_AppArmor.27s_state_on_the_system You can disable the TB AA profile if you are sure you don't want to AppArmor protection for TB by executing the following commandline: $ [ -f /etc/apparmor.d/disable/usr.bin.thunderbird ] || ln -s /etc/apparmor.d/usr.bin.thunderbird /etc/apparmor.d/disable/usr.bin.thunderbird You will need to restart the apparmor package afterwards. But we would like to see the potential source for the blocking by AppArmor to fix and tune the existing profile. $ sudo service apparmore restart Regards Carsten
