I see that the reference message has spawned several previous posts. I installed 20.04 a couple of weeks ago. I read that the message is meaningless. (I followed the link in a response to one of the relevant posts.)

I would like to get a better sense of the potential that the multi-day effort to get my 20.04 installation productive will be fruitful.

Does this message mean I should re-install 20.04, after recreating a live USB?

Thanks, Tim

JIC: A brief history of when I noticed the message.

After fixing a display resolution issue (Software & Updates -> Additional Drivers -> selecting an NVIDIA driver), I started installing software. For some reason the 20.04 installer chose the Nouveau driver from X.org.

After a largish software update (20.04 -> 20.04.1?), the low resolution problem returned, along with system freezes at the motherboard splash screen. I have no idea if there is an association. This happened yesterday.

I was able to re-fix the resolution problem, by again selecting an NVIDIA driver after a (fortunate) successful startup. For some reason the "driver" selected (Software & Updates -> Additional Drivers) had changed to "Manually installed driver" instead of an NVIDIA driver, or the Nouveau driver.

During the several reboots (a couple of them hard), I noticed that the reference message appears on each boot. I do not know if it appeared before my noticing it yesterday.

It is best to ignore the message because it's quite meaningless

If you want to remove it, open initramfs.conf (it is located at /etc/initramfs-tools/initramfs.conf) with sudo vim initramfs.conf.

Look for the line with something along the lines of COMPRESS=....

If "..." says lz4, interchange it with gzip.

If "..." says gzip, interchange it with lz4.

After doing so, update your ramdisk by copying this into a terminal: sudo update-initramfs -u

Then, reboot your computer.

However, it's best to simply ignore the message, as doing the above steps may or may not slow down boot time.

This is possibly because lz4 is faster at decompression than gzip.
