Public bug reported: During latest update of Ubuntu-20.04 focal the following conflict appeared: either ubuntu-advantage-tools must be installed or ttf- mscorefonts-installer must be removed. Such dependence should not be hard, I do not mind (indirect) "recommends" relation.
Since I have no intention to subscribe to ESM or to kernel live patch (sorry, I am not a source of profit for Canonical, at least direct one), I removed ubuntu-advantage-tools and it was working smoothly till the last update. apt upgrade attempted to install new package ubuntu-advantage-tools. I tried to set `Pin-Priority: -1` to this package (I do not recommend such recipe, so no config snippet here). The result is: The following packages have been kept back: python3-update-manager I do not expect upgrade till next year, so I tried to remove packages necessary for dist-upgrade apt purge update-manager-core The following packages will be REMOVED: ttf-mscorefonts-installer* update-manager-core* update-notifier-common* Removing of ttf-mscorefonts-installer is against my goal. I would prefer to keep the fonts. 1. ttf-mscorefonts-installer should not depend on update-notifier- common. I noticed /var/lib/update-notifier/package-data-downloads/ directory in /var/lib/dpkg/info/ttf-mscorefonts-installer.postinst If it is the only reason of dependency, the package may create the directory itself. 2. I hope, there is a way to avoid stale ubutu-advantage-tools without hard dependency in update-manager-core (e.g. "recommends" and some conflicts to earlier versions). I do not know the full story, I found lp:1926361, but fixes released several months ago. I have no idea why the problem appeared on my machine this week. It seems, there 2 independent issues that are quite harmless while isolated but their combination causes a problem. Please, disentangle ttf-mscorefonts-installer and ubuntu-advantage-tools. ** Affects: msttcorefonts (Ubuntu) Importance: Undecided Status: New ** Affects: ubuntu-advantage-tools (Ubuntu) Importance: Undecided Status: New ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New ** Tags: focal ** Also affects: update-manager (Ubuntu) Importance: Undecided Status: New ** Also affects: ubuntu-advantage-tools (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945794 Title: ttf-mscorefonts-installer should not depend on ubuntu-advantage-tools To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/msttcorefonts/+bug/1945794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
