Hi @anon47429100
It sounds like perhaps an update failed to fully install or finish. Normally Ubuntu takes care of this and removes the lock file but it doesn’t appear to have happened for you in this case.
Could you try running these commands in Terminal:
Code:
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
Then try running the updates again.
Let us know if this works
