Ubuntu budge running in Oracle vm in Windows 10.
I am connected to the internet.
When I try to update I get an error popup which says
"Unable to get list of updates.
E: Could not get lock /var/lib/dpkg/lock-frontend - open
(11: resource temporarily unavailable)
But it is not temporary. It keeps happening.
Searching on the internet I forced fsck on reboot by opening the terminal and issuing
shutdown -rF now
This rebooted Ubuntu, did a fdsk on restart and now updates seemed OK. But when I tried again to refresh updates the popup error reappeared.
What does “Could not get lock /var/lib/dpkg/lock-frontend - open” mean and how do I fix it?
