## Waiting for up to <300> seconds for package administration commands to become available (another user is administering packages on zone <XXX>)
- Remove /tmp/.ai.pkg.zone.lock-* from all zones
- Remove /var/sadm/install/.lockfile
- Remove /var/sadm/install/.pkg.lock (<- not sure about this one)
Thank you for your suggestion. It is working but it is not needed to remove the .pkg.lock file. Without this also it is working fine.
