"Failed to check for processor microcode upgrades" at the end of apt-get. How can I fix this?
Solution 1:
All these messages came from needrestart
application which purpose is
check which daemons need to be restarted after library upgrades
This application have several modules. The processor microcode module supports only AMD and Intel processors. So it knows nothing about ARM in the RaspberryPi, so it shows the mentioned error message.
If you do not want to get such messages, then remove this application by
sudo apt-get purge needrestart
or edit relevant configuration file at /etc/needrestart/needrestart.conf
and disable microcode checks completely by changing
#$nrconf{ucodehints} = 0;
to
$nrconf{ucodehints} = 0;
