Sadly I’m already in a crashed state. I do have backups but I can’t restore them as the version change is too big and there are problems of dependencies with gem. I also can’t go back to the old version as launcher pulls automatically, a bit sad imo.

With LC\_ALL I get:

```plaintext
/usr/local/lib/ruby/gems/3.3.0/gems/pups-1.3.0/lib/pups.rb
/usr/local/bin/pups --stdin
/bin/bash: warning: setlocale: LC_ALL: cannot change locale (fr_BE.UTF-8)

```

If I remove LC\_ALL, then the “./launcher rebuild app” stops at :

lc_collate values for database “template1” do not match: old “fr_BE.UTF-8”, new “en_US.UTF-8”

```

With the “manual” docker line mentioned in the top post, I also had to link stuff in /etc/postgresql to /var/… as some files were missing and eventually got the same error than above.

I’ll try a new install and restore there.
