The issue happens if and only if you changed system wide locales after having installed ovirt-engine but before upgrading it to 4.2. I'm going to open a bug to track it.

In engine-setup we are explicitly setting en_US.UTF-8 as the locale of the engine DB but we are not touching at all the locale of postgres own DB which match the system wide locale and your issue is indeed on the postgres DB, not on the engine one. pg_upgrade cannot change it on the fly on upgrades. I tried to find a working fix with env variables but unfortunately nothing I tired worked. The only workaround I was able to find is to temporary set the locale you had at first successful engine-setup execution time (en_US.UTF-8 in your case but it varies) under /etc/locale.conf and only then execute engine-setup to upgrade it to 4.2. After that you could safely switch back /etc/locale.conf to whatever you need. All the env variable I tried seams absolutely not relevant for this specific issue. > >> Best Regards, >> >> Gabriel >> PS: If I go to devconf in Brno I will pay a lot of beers to the >> developer of the engine-setup rollback!
