Have you tried turning it off and on again?

my gf always says that 90% of tech problems can be solved by a restart.

And by my experience- well.. at least 50% xD

@Aitkotw That moment when you find out it was grub you have screwed

Happens al the time as a learning system admin

I found interesting:
I ve worked for a while in a support team for windows clients. Reboot really solves 75% of the cases. Even with windows servers.
Example:
A Service not working, restart the service, still not working. Have a look at event log, no clue what is going on. Restarting system, everything is fine...

After that I continued working with Linux only (thank god🙏) and I never had a problem where I had to restart the kernel to fix it.
Same example,
Have a look at the log file, the service tells you what is wrong, fix it, everything is fine. No restart.
