What were you trying to do that didn't work?
On RHEL 9.7, install an IPA server and a replica, install ipa-healthcheck, then call ipa-healthcheck.
The command fails in the check ipahealthcheck.ds.replication / ReplicationCheck with an exception in lib389/replica.py: module 'datetime' has no attribute 'UTC'
What is the impact of this issue to you?
The command ipa-healthcheck is broken.
Please provide the package NVR for which the bug is seen:
389-ds-base-2.7.0-2.el9.x86_64
python3-3.9.23-1.el9.x86_64
How reproducible is this bug?:
always
Steps to reproduce
- (on master and replica) dnf install -y ipa-server ipa-healthcheck
- (on master) ipa-server-install --domain ipa.test --realm IPA.TEST -a Secret123 -p Secret123 -U
- (on replica) ipa-replica-install --domain ipa.test --realm IPA.TEST --principal admin --password Secret123 -U --server <masterfqdn>
- ipa-healthcheck --source ipahealthcheck.ds.replication --check ReplicationCheck
Expected results
Success
Actual results
The command fails with:
# ipa-healthcheck --source ipahealthcheck.ds.replication --check ReplicationCheck

The lib389 was changed with the rebase to 389-ds-base 2.7 which introduced this commit:
https://github.com/389ds/389-ds-base/commit/62cfa7a8527df167db5793fa29ec270cb06981e6
and changed the method parse_csn (https://github.com/389ds/389-ds-base/blob/389-ds-base-2.7/src/lib389/lib389/replica.py#L920) in src/lib389/lib389/replica.py to use datetime.UTC. The issue is that this attribute was added in python 3.11 (https://docs.python.org/3/library/datetime.html#datetime.UTC) and doesn't exist in python 3.9 which is the version shipped in RHEL 9.7.
