I was reading this in order to learn how to update the dom0 and other qubes templates from the command line.
However, I issued the command
$ qubesctl update.qubes-dom0
but the terminal responded by,
[WARNING] Failed to open log file, do you have permission to write to /var/log/salt/minion?
After that, the terminal prompt was waiting, so I pressed Ctrl+C to interrupt it, assuming the command needed
sudo in front of it.
But now I have QubesOS as a whole being frozen and unresponsive on me.
So, does one need to issue those update commands on the terminal via sudo? And one needs to issue those commands from the dom0 terminal, right?
