I have a fresh install of ispconfig server 3.0.5 on ubuntu 12.04. I have migrated all the websites from ubuntu 10.04.
Now some of the folders of websites in the /var/www/ or /var/www/clients/clientxx/webxx/ have a padlock symbol on it.
I can neither delete or overwrite any files in these locked folder nor I can copy any files in these folders.
for example there is a file in var/www/example.com or /var/www/clients/clientxx/webxx/web.tar.gz.
now I cannot delete web.tar.gz using sudo. I am able to change the permission of web.tar.gz but not for /var/www/clients/clientxx/webxx
root@server1:/home/pawan# chown -R web13:client2 /var/www/clients/client2/web13
chown: changing ownership of `/var/www/clients/client2/web13': Operation not permitted
