Checked the APT package metadata on a 26.04 Resolute test system, and the dependency tree fully confirms the issue:
1. In 26.04, `linux-generic-hwe-24.04` is a transitional package depending solely on `linux-generic-hwe-26.04`. 2. `linux-generic-hwe-26.04` has zero other reverse dependencies in the archive (aside from the transitional 24.04 stubs). 3. `linux-generic-hwe-26.04` recommends `ubuntu-kernel-accessories`, which pulls `intel-microcode`, `amd64-microcode`, and `thermald`. Because the installer image still seeds the 24.04 package as the top-level anchor, it gets marked as manually installed (`manual`), while the actual 26.04 kernel ends up as automatically installed (`auto`). When a user removes the 24.04 stub, APT determines that `linux-generic-hwe-26.04` is an unreferenced orphan. The next `apt autoremove` cleans it out, dragging down the kernel, accessories, and CPU microcode. Updating the germinate desktop seeds in `ubuntu-meta` to seed `linux- generic-hwe-26.04` directly will ensure the native kernel metapackage is marked manual on installation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2167798 Title: Clean 26.04 install marks 24.04 dummy as manual; the real 26.04 kernel ends up as auto; removing dummy wipes the kernel and microcode on autoremove To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/2167798/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
