Ah I think you have a hold (or pin) on brz; and the new solver now considers "brz" as obsolete because the candidate version is not installable anymore, and then tries to prefer to satisfiy
libdpkg-perl Suggests bzr by installing bzr (it does not want to end up with Suggests getting broken by upgrades, so it upgrades Suggests that are currently satisfied to Recommends). Notes: As for obsolete, the goal here was to drive migration towards _new_ packages; i.e. instead of bzr and brz you have libfoo1 and libfoo1t64 (w/ provides on amd64); I don't want the solver to install libfoo1 (or keep it installed) but install libfoo1t64 for you. Now I think this may interact badly with Suggests promotions... The other avenue to explore for me is to have a look at why apt here considers "brz" obsolete in the first place because I just made changes in 2.9.23 to not treat manually installed packages as obsolete... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2102720 Title: Failure: The 3.0 solver produced a worse result To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/2102720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
