There is an issue when I test with update-manager 1:0.156.14.15 (sorry I didn't find the ubuntu bug for update-manager, so I add my comments here).
1. install ubuntu 12.04 on an amd64 machine 2. install the hwe lts-saucy stack 3. enable i386 support 4. install libgl1-mesa-glx-lts-saucy:i386 5. use update-manager to upgrade to the lts-trusty stack Step 5 will fail with an error: The following packages have unmet dependencies: ``` libgl1-mesa-glx-lts-trusty: Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but 10.1.3-0ubuntu0.1~precise1 is to be installed Depends: libx11-6 (>= 2:1.4.99.1) but 2:1.4.99.1-0ubuntu2.2 is to be installed Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-2build1 is to be installed xserver-xorg-lts-trusty: Depends: xserver-xorg-core-lts-trusty (>= 2:1.11) but 2:1.15.1-0ubuntu2~precise1 is to be installed ``` The output of hwe-support-status --show-replacements is: linux-generic-lts-trusty linux-image-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty However since there is libgl1-mesa-glx-lts-saucy:i386 installed we should also put libgl1-mesa-glx-lts-trusty:i386 into the replacements list. In fact for each package in the replacements list we should check if it's also installed for other multiarch and add the lts-trusty replacement to the list too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333728 Title: update-manager should support HWE EOL transition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1333728/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
