Sometimes a cPanel upgrade get hang. To kill all processes, We can simply use these commands instead of manually trying:
killall -9 rpm; killall -9 rpmq; killall -9 yum; killall -9 upcp mv /var/lib/rpm/__db* /root (in case your YUM DB is corrupted) rpm –rebuilddb (to rebuild your cPanel/Yum DB) yum –exclude=kernel* -y update yum clean all
That’s all.
