So occasionally I’ll end up closing out of an update or something else will happen and then next time I use my package manager, I’ll get an error something like this

E: Could not get lock /var/lib/apt/lists/lock – open (11: Resource temporarily unavailable)

Anyway, I’ve found a quick little trick to help this situation.  Type

sudo dpkg –install

And it usually shakes off the nonsense for me.  Don’t know why, but it does.
