Currently enjoying all the hard work people are putting into Mobian. 
Trying to update via GUI and also via command line, but I keep getting
"Could not open lock file /var/lib/dpkg/lock-frontend - open (13 Permission denied)
Unable to acquire the dpkg frontend lock (var/lib/dpkg/lock-frontend) , are you root?"

What to do?

I get that sometimes, I believe it happens the system is running an update on the background(please correct me if I am wrong). But usually waiting a bit and running sudo apt update again works for me.

That's exactly.
Wait some Seconds or repeat your Command until it works.
Works for me allways :-)

Ciao
