Digging a bit further - this machine was manually dist-upgraded on 30-May-2021 (it has -updates enabled, but is set to install only security updates automatically.) That update pulled in libglvnd 1.3.2-1~ubuntu0.20.04.1 (source for libegl1, libglvnd0, etc.)
To upgrade to webkit2gtk 2.34.6-0ubuntu0.20.04.1, u-a must install libopengl0, either 1.3.1-1 from the main archive or 1.3.2-1~ubuntu0.20.04.1 from -updates. However, -updates is not a trusted source for u-a when configured like this, so the only candidate is 1.3.1-1. Unfortunately libopengl0 1.3.1-1 depends on libglvnd0=1.3.1-1, but 1.3.2-1~ubuntu0.20.04.1 is already installed, so u-a would have to downgrade it which is I guess a decision well beyond its pay-grade. I suppose the solution is to find a way to lose the new dependency, obvious answer would be to backport the fixes in webkit2gtk 2.34.6 to 2.34.4? I assume there is some sort of policy on adding new dependencies in security updates? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1963751 Title: focal security update 2.34.6-0ubuntu0.20.04.1 cannot be automatically installed due to new dependency Status in unattended-upgrades package in Ubuntu: Incomplete Bug description: Version: 2.34.6-0ubuntu0.20.04.1 This security update for focal does not seem to be automatically upgradeable by unattended-upgrades: 2022-03-05 14:32:35,653 WARNING package libwebkit2gtk-4.0-37 upgradable but fails to be marked for upgrade (E:Unable to correct problems, you have held broken packages.) 2022-03-05 14:32:36,685 WARNING package libwebkit2gtk-4.0-37 upgradable but fails to be marked for upgrade (E:Unable to correct problems, you have held broken packages.) 2022-03-05 14:32:38,031 INFO No packages found that can be upgraded unattended and no pending auto-removals 2022-03-05 14:32:38,232 INFO Package libjavascriptcoregtk-4.0-18 is kept back because a related package is kept back or due to local apt_preferences(5). 2022-03-05 14:32:38,382 INFO Package libwebkit2gtk-4.0-37 is kept back because a related package is kept back or due to local apt_preferences(5). apt-mark showhold lists no held packages, and there are no apt_preferences set.
