Another application holding yum lock.

Many a times it so happens that when you trying to do some stuff with yum command when you are connected to internet.It shows

“Another app is currently holding the yum lock; waiting for it to exit…”

you can resolve that by following the command

# ps aux | grep yum

This shows you the processes holding the yum lock.

Now you can do:

# kill -9 31542
# kill 31542

or whatever the processes may be.

Now your yum will work fine.
