i am getting same error,I think i have removed some essential directories while un-installing apache 2 . Anybody please help me to recover the files and to install apache 2.

Answer 1

Finally i solved the error by running commands-

sudo apt-get clean && sudo apt-get autoclean
sudo apt-get purge apache2
sudo apt-get install apache2

Answer 2

No need to reinstall apache2<\/code> (and with purge<\/code> deleting all configs). Just do:

sudo apt-get purge javascript-common 
sudo apt-get install javascript-common
