I'm running a Plesk server on AWS latest infrastructure (May, 2021) which I have upgraded from Ubuntu 18.04 to 20.04, in accordance to the Plesk guidance.

During this upgrade process I got the below error message:

could not get modinfo from 'crc32' as there was no such file or directory

SSH Print Screen

I do have at the moment crc32 module installed:

# lsmod | grep crc
libcrc32c              16384  4 nf_conntrack,nf_nat,btrfs,raid456

# dpkg -l | grep linux-modules | grep "ii  "

May I ask:

  1. What was it that went wrong?

  2. How can I diagnose the issue? and,

  3. What should be done to fix it?

  • Hi @guiverc, There are Ubuntu 18 (which is 18.04) and Ubuntu 20 (which is 20.04), as can be seen here: support.plesk.com/hc/en-us/articles/… It's a bit strange as by "Also asked at" you were pointing to the URL of this exact same page. Possibly you were referring to the Post system: ubuntuforums.org/showthread.php?t=2462391 As I considered this as being legitimate and pluralism of ideas, may I ask if this is consider less acceptable over here?

  • No Ubuntu has had products that use yy format, they are snap only products such as Ubuntu Core 18 so Ubuntu 18 implies a snap only release where dpkg and apt are invalid commands (deb packaged systems use the yy.mm format). It's been that way since 2016. The snap only systems are smaller which is a plus for devices/appliances, and cloud use (faster to spin up & need less resources), plus have 10 years of supported life (double that of LTS releases, though less if ESM is included). Sorry I'll meant to use ubuntuforums.org/showthread.php?t=2462391

  • Canonical is the company behind Ubuntu; the Ubuntu community likewise know what the releases are; just because a 3rd party site (support.plesk.com) says something incorrect - it's not fact (it's a warning they don't know the product very well as they're mixing up two different products!) thus I'd use that as a sign to be careful of their advice.. Everyone makes mistakes, but in a careless guide like that shows sloppiness. FYI: If you upgrade Ubuntu Core 18 to Ubuntu Core 20; no apps need changing as snaps are the same all releases! (recall they don't use deb packages!)

  • I got this message also after running apt-get upgrade. Following the link and the advice at the other page I ran ` sudo update-initramfs -u`, which completed quickly, but I don't know if it tackled the issue (or even what it did at all).
