Reopen Issue

When I try to uninstall a middle replica in a line topology under domainlevel 1 so that the installation would disconnect remote replica from master, the uninstallation fails, but the returncode is 0.

# ipa-server-install --uninstall -U
WARNING: This IPA master is still a part of the replication topology.

Aborting uninstallation
# echo $?
0

Can you please double check that it is indeed the ipa-server-install command that returns the 0 exit code in this scenario?

The relevant code part goes as follows:

        print("Aborting uninstallation")
        sys.exit(1)

There really isn't much chance of us exiting with other than exit code 1, as far as I can see.

mbabinsk: able to reproduce with current master, the SystemExit is caught and consumed somewhere, see http://fpaste.org/336766/57622491/

The link from mbabinsk does not work anymore so I'll describe the problem here.

The fix may not be that trivial. The problem is that the control flow moves from ipapython/install/core.py:372 to ipapython/install/common.py:91 which eventually ends up with the error just being logged and as the control gets back to core.py:372. The state is then set to _FAILED but I'm not sure if this is ever checked in the ongoing magic.
