Can confirm https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1835660/comments/26 What I did was I changed
`COMPRESS=lz4` to `COMPRESS=gzip` in `/etc/initramfs-tools/initramfs.conf`, then `sudo update-initramfs -u` After, without a reboot I've changed `COMPRESS` back to `lz4`, and then `sudo update-initramfs -u` And after the reboot that error is gone. -- 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
