This is a simplified version of the means to work around this problem: Step 1: sudo sed -i 's/COMPRESS=lz4/COMPRESS=gzip/g' /etc/initramfs-tools/initramfs.conf
Step 2: sudo update-initramfs -u Step 3: Reboot. Now I wonder whether someone has already tried something other than gzip? Because initramfs.conf mentions no less than six options: # COMPRESS: [ gzip | bzip2 | lz4 | lzma | lzop | xz ] Apparently gzip is slower than lz4, which might slow the boot process by several seconds. One of the other alternatives might be faster. Of course I could test that myself, but I'm too lazy today, so I'm hoping somebody else has done the footwork already.... -- 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
