I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back.

I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically?

If not, which directories do I have to create in /var/cache/ manually to let everything work fine?

I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there.

I hope somebody can guide me to fix this issue.
