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!
Can anyone explain what these messages mean?
Is there any workaround for this that will enable Software Updated to complete more quickly?
