[08:16] <flxfoo> hi all
[08:16] <flxfoo> I have a bit of an issue.
[08:17] <flxfoo> I upgraded some controller/models to my latest current version (2.9.42) on dev platform.
[08:18] <flxfoo> Production is 2.8. And documentation tells that before version 3.x one can use `upgrade-controller` and `upgrade-model`
[08:18] <flxfoo> now the upgrade is stuck on some mongodb database upgrade
[08:18] <flxfoo> with this message
[08:18] <flxfoo> ERROR juju.worker.upgradedatabase worker.go:356 database upgrade from 2.8.0 to 2.9.42 for "machine-0" failed (will retry): add spawned task count to operations: cannot find document {actions 61909253-939f-48c0-8452-389111410e43:10} for applying transaction 5ef73fe0f769b403ba6ea62a_dde833fc
[08:19] <flxfoo> Is there something I can do from here, upgrade still retrying without success
