Error: Another app is currently holding the yum lock

Hi,

I am using Fedora 17 LXDE 32+ bit distro and this is error I am getting in a terminal when I try to install a package being root. Thanks.

Try entering ps -p1686 in a terminal - that'll tell you which process is holding the lock.

If you feel it shouldn't be, you can kill the process (kill 1686), but obviously you want to be careful about this in case the process is in the middle of something!

Edit: Apologies; forgot that it already says yum has the lock. Too early for me; my cup of tea hasn't kicked in The second half of my reply stands though; if you're sure that you don't already have an instance of yum open somewhere else (remembering to allow for GUI package managers etc), you can consider killing it - on your own head be it though!

sudo yum-complete-transaction

that should take care of it.

Thanks you friends, here is what I did and it worked...

ps aux | grep yum

Then I killed the process

ps -e | grep yum
kill -SIGKILL 1686

Yeah, another way is to go into your system monitor and kill yum.
