per test again today with stock ubuntu image, it behaves differently from oem image.
On the update-manager, there will be two button 'Continue' and 'Partial Upgrade' (check attached picture) I click Continue first, it does not install any package that's related to fwupd. After that, the windows with two button appears again. I click "Partial Upgrade" again, it show me that it will 1. remove fwupdate-siged and libfwupd1 2. upgrade: fwupdate (the transitional package) and fwupd. 3. install: fwupd-signed. with other packages in the proposed channel. I click "Start Upgrade" to proceed, it ends up with. 1. fwupd, fwupd-signed, libfwupd2, fwupdate install. 2. fwupdate-signed remove (status: rc, which means config file need to be purged.) The test result seems to be the one we want it to be. Next: will confirm why oem image behaves differently. ** Attachment added: "update-manager-partial-update_continue.jpg" https://bugs.launchpad.net/oem-priority/+bug/1820768/+attachment/5313203/+files/IMG-4293.jpg ** Tags removed: verification-failed-bionic ** Tags added: verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820768 Title: [SRU] support new cab and new docking firmware upgrade in fwupd 1.2.10 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1820768/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
