Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem: ipa-replica-install should handle keyboard interrupt gracefiully rather than throwing traceback.
Version-Release number of selected component (if applicable):
ipa-server-4.4.0-8.el7.x86_64
How reproducible: Always
Steps to Reproduce:
1. Install ipa-server.
2. Install replica server using the command
#ipa-replica-install -P admin -w Secret123
3. Try to do a Ctrl+C before the command is sucessfully completed.
Actual results: Traceback is thrown on the console.
[root@replica ~]# ipa-replica-install

KeyboardInterrupt
ipa.ipapython.install.cli.install_tool(Replica): ERROR The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information
Expected results: Handle keyboard interrupt for the command.
Additional info:
IdM team doesn't have capacity to fix this bug for RHEL 7.4. Moving to next RHEL version. Fixing the bug there will depend on capacity of FreeIPA upstream. Without sufficient justification there is a chance that it will be moved again later.
So I looked again. Basically we'd have to wrap the entire thing, imports and all, in a try/except KeyboardInterrupt to capture every possible catchable interrupt. IMHO it's not worth it. This is a rare event.
