My computer crashed during the upgrade from 14.04 to 16.04 and since then I receive this message when I get to the command line.This is the command I used for the upgrade
sudo update-manager -d
How can I resolve this?
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
This might be frowned upon, but you could try deleting the lock file... then re-attempting the upgrade:
sudo rm /var/lib/dpkg/lock
you can delete the lock file with the following command:
sudo rm /var/lib/apt/lists/lock
You may also need to delete the lock file in the cache directory
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
After that, try opening Synaptic again.
