Issue

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 [ { "source": "ipahealthcheck.ds.replication", "check": "ReplicationCheck", "result": "CRITICAL", "uuid": "18b55700-a406-4b2f-ada0-4a1235b542ac", "when": "20250701081923Z", "duration": "0.352202", "kw": { "exception": "module 'datetime' has no attribute 'UTC'", "traceback": "Traceback (most recent call last):\n  File \"/usr/lib/python3.9/site-packages/ipahealthcheck/core/core.py\", line 56, in run_plugin\n for result in plugin.check():\n  File \"/usr/lib/python3.9/site-packages/ipahealthcheck/core/plugin.py\", line 18, in wrapper\n for result in f(*args, **kwds):\n  File \"/usr/lib/python3.9/site-packages/ipahealthcheck/ds/plugin.py\", line 108, in check\n results = self.doCheck(self.check_class, self.many)\n  File \"/usr/lib/python3.9/site-packages/ipahealthcheck/ds/plugin.py\", line 97, in doCheck\n for result in results:\n  File \"/usr/lib/python3.9/site-packages/lib389/_mapped_object_lint.py\", line 126, in lint\n yield from f()\n  File \"/usr/lib/python3.9/site-packages/lib389/replica.py\", line 1325, in _lint_no_ruv\n ruv_dict = ruv.format_ruv()\n  File \"/usr/lib/python3.9/site-packages/lib389/replica.py\", line 949, in format_ruv\n \"csn\": RUV().parse_csn(self._rid_csn.get(rid, '00000000000000000000')),\n  File \"/usr/lib/python3.9/site-packages/lib389/replica.py\", line 920, in parse_csn\n time_str = datetime.datetime.fromtimestamp(timestamp, datetime.UTC).strftime('%Y-%m-%d %H:%M:%S')\nAttributeError: module 'datetime' has no attribute 'UTC'\n" } } ] 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.
