Ubuntu Debian – How to Restore /var/cache/apt Structure After Deletion

aptdebianpackage-managementUbuntu

I was running out of space on an Ubuntu server, so I did this command to save space

sudo rm -rf /var/cache/apt/archives

However now when trying to do things with apt, I get the following errors:

E: Could not open lock file /var/cache/apt/archives/lock - open (2 No such file or directory)

E: Unable to lock the download directory

And things like 

Archive directory /var/cache/apt/archives/partial is missing.

Clearly I have removed some directory structure. Is there some way to do a apt-get rebuild-var-tree or similar?

You need two things there: 

sudo mkdir -p /var/cache/apt/archives/partial
sudo touch /var/cache/apt/archives/lock
sudo chmod 640 /var/cache/apt/archives/lock

Removing this directory manually is a bad idea generally. To clean archives cleanly, use:

sudo apt-get clean
