Fix sudo yum hang problem with no output or error messages
Encounter a weird error this morning while trying to execute sudo yum update command. Yum just hangs there and no error messages whatsoever were displayed on screen. Have to issue kill -9 to terminate the yum process.
To fix the problem, first :
cd /var/lib/rpm
and then remove the __db.00* files. All of them.
and run this command
/usr/lib/rpm/rpmdb_recover
Run the sudo yum update command again and everything back to normal again!
Hope this helps.
