After reboot, base system operates fine, but Thunderbird and Firefox fail to open. As far as I can tell, these are the only applications affected. Tried to file a ubuntu-bug report but Firefox was the default browser, so that failed as well. I switched to Chromium as default and the bug report succeeds. Launching either Firefox or Thunderbird in Safe Mode from the terminal succeeds. As a troubleshooting step, I attempted to Mark All Upgrades, only files available were: apt (2.0.6) to 2.0.8 apt-utils (2.0.6) to 2.0.8 libapt-pkg6.0 (2.0.6) to 2.0.8 login (1:4.8.1-1ubuntu5.20.04.1) to 1:4.8.1-1ubuntu5.20.04.2 passwd (1:4.8.1-1ubuntu5.20.04.1) to 1:4.8.1-1ubuntu5.20.04.2 Of special note: yesterdays automatic updates do not appear in Synaptic History. The only updates which appear in recent History are the ones I manually applied. They do appear when using : find /var/lib/dpkg/info/ -name \*.list -mtime -3 | sed 's#.list$##;s#.*/##' This produces this list: mesa-vulkan-drivers:amd64 systemd-sysv gnome-control-center libc6-dbg:amd64 mesa-va-drivers:amd64 libpcre3:i386 libpam-systemd:amd64 libldap-2.4-2:amd64 apport python3-apport libc6-i386 libc6:amd64 libpcre3:amd64 systemd-timesyncd libdrm-common libxatracker2:amd64 gnome-control-center-faces libegl-mesa0:amd64 udev libdrm-intel1:amd64 sbsigntool libc6-dev:amd64 libc6:i386 libglapi-mesa:amd64 libldap-common login libdrm-nouveau2:amd64 systemd ubuntu-advantage-tools gnome-control-center-data mesa-vdpau-drivers:amd64 libdrm-amdgpu1:amd64 openssh-client libtiff5:amd64 apt-utils locales python3-problem-report libtiff5:i386 apt libapt-pkg6.0:amd64 apport-gtk libc-dev-bin libdrm-radeon1:amd64 libgbm1:amd64 libsystemd0:i386 libsystemd0:amd64 libdrm2:amd64 libgl1-mesa-dri:amd64 libc-bin libxml2:amd64 passwd libudev1:i386 libnss-systemd:amd64 libudev1:amd64 libglx-mesa0:amd64 libxml2:i386 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: ubuntu-release-upgrader-core 1:20.04.38 ProcVersionSignature: Ubuntu 5.13.0-40.45~20.04.1-generic 5.13.19 Uname: Linux 5.13.0-40-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.24 Architecture: amd64 CasperMD5CheckResult: skip CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Wed May 18 14:58:07 2022 InstallationDate: Installed on 2020-08-05 (650 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) PackageArchitecture: all SourcePackage: ubuntu-release-upgrader Symptom: release-upgrade UpgradeStatus: No upgrade log present (probably fresh install) VarLogDistupgradeAptlog: Log time: 2021-08-22 16:56:14.687667 Starting pkgProblemResolver with broken count: 0 Starting 2 pkgProblemResolver with broken count: 0 Done None To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1974079/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
