Issue
I have changed my hostname in linux mint and after that my sudo works slow I mean how to change the etc/sudoers back again to work properly or there is anything else that I have to change
Solution
you probably need to edit /etc/hosts to reflect your new hostname
otherwise it tries to find info about it via DNS (and timeouts, most probably)
look for:
127.0.0.1 localhost oldname
and change to:
127.0.0.1 localhost newname
Of course change only the line corresponding to oldname. Above I gave an an example of a machine which isn't connected to the net...
Below I give an example of a machine which have an IP:
127.0.0.1 localhost
a.b.c.d oldname <-- just edit that line
