[Nebula-users] DONE: Nebula downtime for updates Tuesday 2022-06-21 at 16-17 CEST

[Kent Engström]

The downtime below completed in time and you are welcome back in.

During this, we also made to small changes that we want to inform you
about:

- Nebula no longer accepts locale-related variables (LANG, LC_CTYPE etc)
  being forwarded over SSH when you log in.

- Nebula sets LANG=en_US.UTF-8 instead of LC_CTYPE=sv_SE.UTF-8 to be
  more compatible with normal RHEL 7 / CentOS 7 systems.

We do not think this will cause problems for you, but if you need
something else, please set it yourself in your shell init files
