Failed to start apache Can't open /etc/apache2/envvars

i have had this problem a couple of times now and i am not sure what is causing it

Failed to start apache : .: 45: Can't open /etc/apache2/envvars

when i look at a dir listing, i get these question marks next to envvars, does anyone know what that means?

os is ubuntu 10 if that helps
