That command has something to do with firmware. That's all I know.
See this for info: Ubuntu Manpage: fwupdmgr - Firmware update manager client utility
it is generally safe to use the
fwupdmgr --force refresh command. This command simply instructs the
fwupdmgr tool to check for any new firmware updates, even if it thinks it has already checked recently. The
--force option tells the tool to refresh the firmware update metadata even if it believes it has already done so.
However, it is always a good practice to ensure that you have a stable power supply and a backup of your important data before performing any updates or refreshes, just to be safe. It is also a good idea to make sure that you are using the latest version of the
fwupdmgr tool to ensure that any known issues have been addressed.
I second the post made by @nfratom
The command is a safe command, but this does not mean that running it is the solution to your problem or applicable to your situation.
firmware updates usually add compatibility for new devices or fix the bugs related to a hardware and thus can fix hardware problems. but i won't recommend updating the firmware unless u are having an issue with ur computer hardware, since updating firmware is a risky process and if it gets interrupted u can end up with a dead computer
computer will not even boot up if firmware updates fails
Start by pushing the power button ..... turning your computer on .....
Thanks @Frog !
