I've been experiencing this for several months now (not exactly sure when it started). For me, the error leads to a hard stop and the option to Ctrl-D to continue or ENTER for maintenance.
I followed the process from #47 (Saroumane wrote on 2020-04-06:) Adding COMPRESS=gzip to /etc/initramfs-tools/initramfs.conf (instead of lz4) then: sudo update-grub;sudo update-initramfs -c -k all;sudo update-grub Reboot. Still got error message. I restored COMPRESS=lz4 then sudo update-grub;sudo update-initramfs -c -k all;sudo update-grub Reboot Still failed systemd-analyse says : Startup finished in 158us (firmware) + 568us (loader) + 2.027s (kernel) + 1min 31.97s (userspace) = 1min 33.999s graphical.target never reached I can eventually get back into the system through a combination of multiple reboots and dumb luck, but this is pretty annoying. I rebooted a 3rd time : no change, still no more Decoding errors. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed Status in initramfs-tools package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Bug description: "initramfs unpacking failed: Decoding failed", message appears on boot up. If I "update-initramfs" using gzip instead of lz, then boot up passes without decoding failed message. --- However, we currently believe that the decoding error reported in dmesg is actually harmless and has no impact on usability on the system. Switching from lz4 to gzip compression, simply papers over the warning, without any benefits, and slows down boot. Kernel should be fixed to correctly parse lz4 compressed initrds, or at least lower the warning, to not be user visible as an error.
