The missing linux-update-symlinks script seems like it's supposed to come from linux-base, which appears to exist with the same version number (4.5ubuntu1~16.04.1), yet different contents, in xenial (no linux-update-symlinks) and xenial-updates. It appears that this is because 4.5ubuntu1 is getting picked up from xenial-security, but the packages.ubuntu.com filelist isn't showing this; xenial actually seems to debootstrap 4.0, not 4.5ubuntu1~16.04.1.
https://packages.ubuntu.com/xenial/all/linux-base/filelist https://packages.ubuntu.com/xenial-updates/all/linux-base/filelist https://launchpad.net/ubuntu/xenial/+source/linux-base So I *think* (just from first bit of this research, not from actually trying a fix) it might as simple as the linux-base dependency in linux- image-4.4.0-143 needing a version constraint >= 4.5, to force apt to upgrade linux-base first. That certainly seems appropriate in any case, as the script it's planning to call isn't in 4.0 package. The upgraded package is seemingly available (from security or from xenial-updates), but there's no constraint telling apt it must seek it out, and what it already has meets the stated dependency so it's just proceeding with it. As far as workarounds this theory might suggest, I'm not sure if there's a way to get d-i to include xenial-updates in the debootstrap sources so it would just get it the newer one in the first place (which would also avoid the redundancy of downloading/installing old versions and then immediately upgrading it). I had hoped that using `d-i pkgsel/upgrade safe-upgrade` might be another way to get it to install the upgraded linux-base before proceeding to the kernel, but it doesn't happen early enough. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820755 Title: Netboot install fails due to linux-image-4.4.0-143-generic.postinst linux-update-symlinks not found To manage notifications about this bug go to: https://bugs.launchpad.net/bluelinux/+bug/1820755/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
