Error: Transaction failed

• Root cause: The infrastructure-agent package installation fails due to a stale shadow.lock file. This lock prevents simultaneous modifications to the password file (/etc/shadow) during the upgrade process.

Solution Copied

• The issue was resolved by removing the shadow.lock file located at /etc/shadow.lock directory.
