I have a laptop which over the years I have upgraded from Ubuntu 14.04 LTS to 20.04. I tend to run Software Updater within minutes of receiving notification. Usually this process takes about 5 minutes. Today it took at least 45 minutes. When updating linux-firmware, the process took at least 60 seconds to execute each of dozens of instances of older kernel versions and displayed messages like this:

modinfo: ERROR: could not get modinfo from 'crc32': No such file or directory
E: amd64-microcode: unsupported kernel version!
  1. Can anyone explain what these messages mean?

  2. Is there any workaround for this that will enable Software Updated to complete more quickly?

  • Do you have a 32-bit laptop? You may have had 14.04 32-bit installed on the laptop. The new Ubuntu releases are only 64-bit, although you can get 32-bit variants still from other distros. The 'amd-64' code refers to 64-bit architecture. It's telling you that your computer doesn't support that kernel possibly due to not having a 64-bit computer. But I may be wrong about that. – Lumbeezl Jan 6 at 14:11
  • remove older kernels. – nobody Jan 6 at 14:37
  • This is definitely a 64-bit computer, as confirmed by Settings/About/OS Type. – James E Keenan Jan 7 at 15:39
