Package: thunderbird Version: 1:68.2.2-1~deb10u1 Followup-For: Bug #928178 Not sure this is the same bug, but the symptom is similar, and the solution is the same...
After upgrade to Debian 10.2 "Buster" (and possibly some additional factors, but see below) Thunderbird would not start. It would pop up a dialog "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible". When started from the console, it would also print "Error: Access was denied while trying to open files in your profile directory." I initally noticed this from a user account that has its $HOME on an NFS server, server running Debian 8 "Jessie"; so I tried a few things: * Move ~/.icedove and ~/.thunderbird out of the way: same error * Start "thunderbird -P" (profile manager): same error * Remove ("dpkg --remove") the apparmor package: same error * Create a new user with $HOME also on NFS: same error * Create a new user with $HOME under /var: same error However, it worked again after I ran the command "aa-disable /etc/apparmor.d/usr.bin.thunderbird". -- System Information: Debian Release: 10.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-6-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages thunderbird depends on: ii debianutils 4.8.6.1 ii fontconfig 2.13.1-2 ii libatk1.0-0 2.30.0-2 ii libc6 2.28-10 ii libcairo-gobject2 1.16.0-4 ii libcairo2 1.16.0-4 ii libdbus-1-3 1.12.16-1 ii libdbus-glib-1-2 0.110-4 ii libevent-2.1-6 2.1.8-stable-4 ii libffi6 3.2.1-9 ii libfontconfig1 2.13.1-2 ii libfreetype6 2.9.1-3+deb10u1 ii libgcc1 1:8.3.0-6 ii libgdk-pixbuf2.0-0 2.38.1+dfsg-1 ii libglib2.0-0 2.58.3-2+deb10u2 ii libgtk-3-0 3.24.5-1 ii libgtk2.0-0 2.24.32-3 ii libjsoncpp1 1.7.4-3 ii libpango-1.0-0 1.42.4-7~deb10u1 ii libstartup-notification0 0.12-6 ii libstdc++6 8.3.0-6 ii libvpx5 1.7.0-3+deb10u1 ii libx11-6 2:1.6.7-1 ii libx11-xcb1 2:1.6.7-1 ii libxcb-shm0 1.13.1-2 ii libxcb1 1.13.1-2 ii libxext6 2:1.3.3-1+b2 ii libxrender1 1:0.9.10-1 ii libxt6 1:1.1.5-1+b3 ii psmisc 23.2-1 ii x11-utils 7.7+4 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages thunderbird recommends: ii hunspell-ar [hunspell-dictionary] 3.2-1.1 ii hunspell-ca [hunspell-dictionary] 3.0.3+repack1-1 ii hunspell-de-at [hunspell-dictionary] 20161207-7 ii hunspell-de-ch [hunspell-dictionary] 20161207-7 ii hunspell-de-de [hunspell-dictionary] 20161207-7 ii hunspell-en-gb [hunspell-dictionary] 1:6.2.0-1 ii hunspell-en-us [hunspell-dictionary] 1:2018.04.16-1 ii hunspell-eu [hunspell-dictionary] 0.5.20151110-4 ii hunspell-fr-classical [hunspell-dictionary] 1:6.3-2 ii hunspell-gl [hunspell-dictionary] 1:6.2.0-1 ii hunspell-hr [hunspell-dictionary] 1:6.2.0-1 ii hunspell-it [hunspell-dictionary] 1:6.2.0-1 ii hunspell-kk [myspell-dictionary] 1.1-2 ii hunspell-kmr [hunspell-dictionary] 1:6.2.0-1 ii hunspell-ko [hunspell-dictionary] 0.7.1-1 ii hunspell-lt [hunspell-dictionary] 1:6.2.0-1 ii hunspell-pl [hunspell-dictionary] 1:6.2.0-1 ii hunspell-pt-br [hunspell-dictionary] 1:6.2.0-1 pn lightning <none> ii myspell-es [myspell-dictionary] 1.11-15 ii myspell-he [myspell-dictionary] 1.4-3 ii myspell-uk [myspell-dictionary] 1.7.1-2 Versions of packages thunderbird suggests: ii apparmor 2.13.2-10 ii fonts-lyx 2.3.2-1 ii libgssapi-krb5-2 1.17-3 -- no debconf information
