Ubuntu

login redirects me back to login screen

Asked by Brian Marine

my login screen bounces back to itself, everything i tried (including chown -R $USER:$USER $HOME, though im not sure if i types it right, my username is nomad). if i try using sudo command i get
sudo: /usr/lib/sudo/sudoers.so must be only writable by owner
sudo: fatal error, unable to load plugins

before this happened i used sudo nautilus in a terminal and changed permissions in the / directory to transfer files, but then as soon as i closed it i check the permissions and they seemed the same as before.

What is the outcom of this command?
ls -l /usr/lib/sudo/sudoers.so
When changing the permissions of the root directory I hope you have not changed the permissions of all sub directories because this would be a very bad thing.

incase it helps, i have a second partition with ubuntu in it too, so we could possibly use that for something we need to fix this.

Hello,

open a terminal and try

    pkexec chmod 644 /usr/lib/sudo/sudoers.so

Then check the results of

    stat -c "%a,%n" /usr/lib/sudo/sudoers.so
