I did a clean install of 20.04 on my machine (which has been running Ubuntu, most recently 19.04, without issue so far) and I am facing this - importantly in my case it is NOT a harmless message but actually preventing boot - I am stuck in the initramfs prompt.
I tried the suggested workaround of editing "/etc/initramfs- tools/initramfs.conf" to specify COMPRESS=gzip instead of COMPRESS=lz4 to no avail (issue remains on next boot attempt). I can not run try elsewhere also suggested "sudo update-initramfs -u" command because as I understand it I am lacking the proper context in which this would be run - in the initramfs prompt I can not run it (or at least don't know how), and if I boot into live ubuntu (which works perfectly - this is also where I was able to edit the initramfs.conf file) I could probably run this although it would be in the wrong context (that of the live ubuntu, not the one on disk I installed previously). Thanks everyone for the effort to resolve this! I'll run 19.10 or another distro in the meantime and hope this can be resolved soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1835660/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
