Description

Recently there are issues with yum db updates after cleaning up caches:

Transaction test succeeded

This fix will completely wipe out yum db before rebuild during startup.

Also issues with another process taking apt/apt-get in ubuntu:

E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 6190 (unattended-upgr)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

This will remove any existing apt/apt-get process before upgrade.

Note that ubuntu update automatically will happen and I didnt disable that in case there are new updates showing up after the initial startup.

Can you confirm if this change is tested. Just in case we break other things while fixing one.
Thanks!
