Postgres FATAL: invalid value for parameter "TimeZone": "Europe/Kyiv"

Postgres container will not initiate the Nextcloud database because of Timezone error
psql: error: ... FATAL: invalid value for parameter "TimeZone": "Europe/Kyiv"

A workaround is to keep the nextcloud-aio-mastercontainer and remove all the other AiO containers and their PVs. And start them again with some other TZ.

The problem and the workaround are for Nextcloud AiO setup inside docker container environment. However can be adopted for any other Nextcloud implementation

Most *nix OSes still have an outdated timezone lists. So the AiO setup wizard statement " You can get valid values by looking at the ‘TZ database name’ column of this list: click here." is a kind of misleading. IANA had updated the TZ data for Ukrainian cities years ago, but it takes time to propagate. Keep reporting, keep pushing though! “Boritesia - poborete” :wink: (c)

Workaround steps:

  1. Login to https://<your-nc-domain.tld>:8443/containers
  2. Stop containers
  3. Keep the nextcloud-aio-mastercontainer and remove all the other AiO containers and their PVs
  4. If your server is to be multinational, use UTC +0 and save the hassle :smiley: . Or else, change timezone to some capital with the same TZ (and same DST!!!) as yours. For Ukraine/Kyiv it can be Helsinki, Tallinn, Riga, Vilnius, Chisinau, Bucharest, Sofia*, Athens.
  5. Refresh the AiO page!
  6. AiO will find out that the containers are missing and will offer something like: “:warning: Container updates are available … Start and update containers”, which in these very case means to initiate new containers and PVs for them
  7. Check the database container logs - they should look much better now :slight_smile:
  8. Be patient - it may take a long time for main Nextcloud container to initiate. (follow the logs :person_in_lotus_position: )

:warning::warning::warning: be very careful and think twice if you are adopting thise workaround for a running Nextcloud with your data inside :warning::warning::warning:

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

Hm… Does Europe/Kiev work?

It’s a rhetorical question since 2014 at least. Too much pain and anger in it. Not a place to discuss.

I only wanted to suggest this as a workaround
