[SOLVED] initramfs unpacking failed: Decoding failed

[gungosh]

Change COMPRESS=lz4 to COMPRESS=gzip

Thank you.

I'd like to add that I also can confirm this bug comment on my notebook
- change to gzip
- update
- don't boot
- change back to lz4
- update
- boot
- no error message

Tried all the solutions but after regenerating iniramfs I get this error:

Code: Select all

update-initramfs: Generating /boot/initrd.img-5.4.0-60-generic
cp: cannot stat '/var/lib/acpi-override/*': No such file or directory
E: /usr/share/initramfs-tools/hooks/acpi-override failed with return 1.
update-initramfs: failed for /boot/initrd.img-5.4.0-60-generic with 1.

Did you do the update with

Code: Select all

sudo update-initramfs -u

Yes, the error messages occur when updating initramfs...

Did you try going back to lz4? Do you have a Timeshift restore snapshot?

[inot12]

Solution that worked for me:

Recently installed MATE 20 and the message showed during first boot session. Immediately after that I applied the proprietary graphics driver through Driver Manager. A reboot or two later I noticed that the message was gone.

Today I updated the kernel and the message showed up again. I tried to reapply the proprietary graphics driver and the message was gone:

Apply open source driver.
Reboot.
Reapply proprietary driver.
Reboot.

cat /etc/initramfs-tools/initramfs.conf still shows COMPRESS=lz4.

Hope this helps.

Yes, I went back to lz4. I did a fresh install of LM 20 and right after the install the message appeared so I have no snapshot to restore.

I created an empty file and put it at /var/lib/acpi-override/
The error is gone now but I don't know if something is corrupt now. In this bug the submitter says the script tries to copy files from a directory but there is nothing to copy and so the error message will appear. By creating the empty file this error is skipped and the script will finish.

That did not work for me. I am using an Nvidia graphics card which is somehow problematic to install in LM, so I won't touch the video driver anymore.

Clean install using Edge iso Mint 20.1 Cinnamon, I am not getting the error even after today's kernel 5.8 updates with lz4.

Code: Select all

sudo cat /etc/initramfs-tools/initramfs.conf

Returns

Code: Select all

# COMPRESS: [ gzip | bzip2 | lz4 | lzma | lzop | xz ]
#

COMPRESS=1z4

And

Code: Select all

lance@LM:~$ dmesg -l emerg,alert,crit,err
lance@LM:~$ 

However both my other systems that were upgraded from Mint 20 to 20.1 have the error with

Code: Select all

 lz4

I may try going with 5.8 kernel on one of them to see.

Well, I tried it with the newest 5.8 Kernel in Update Manager on the upgraded 20.0 to 20.1 Cinnamon, and with lz4 the error is still there. I put it back with Timeshift to Kernel 5.4 and gzip with Timeshift.
