Somehow, permission in my Fedora got messed up. I don't see root is owner of /usr/bin/sudo directory and I am not able to execute any command using sudo. I am trying to find a solution but the solution I am seeing Ubuntu specific. Can some one please provide me steps to fix in Fedora.
Error:
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
Boot to recovery mode or log in as root if you can and run:
chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo
same as with Ubuntu.
You may have other problems with permissions and ownership, one advantage of .rpm systems however is you can chack and reset them easily:
for p in $(rpm -qa); do rpm --setugids $p; done
for p in $(rpm -qa); do rpm --setperms $p; done
See man rpm or https://www.cyberciti.biz/tips/reset-... for details
Do run the setugids before running setperms, as modifying the uid and gid will clear the suid and guid bits in the perms.

Do you have some other way than sudo to get root access? Root privileges of some form are certainly necessary for fixing those sudo permissions.
Try ctrl-alt-f2 to get to text terminal, login as root, and correct the permissions settings from there.
