Steps to Reproduce

Install. Choose English language
Enable SSH and log in
Various commands generate locale errors, e.g. sudo apt install mc (after, sudo apt update), sudo dpkg-reconfigure tzdata or I see these a lot when building software using the autotools

Additional Information

I live in Spain, so perhaps the locale is set to British English based on my location.

Fix

Make sure the locale is included/uncommented in /etc/locale.gen and regenerate locales with sudo locale-gen

Issue still exists in the release version of Volumio 3

Here is an example on the command line

Here is an example using mc

This happens only when using a terminal for some background work, which is not a typical Volumio use case.
I think the Volumio Team did/ does not see this as an urgent issue to resolve.

ashthespy · December 10, 2021, 12:55pm

I recall fixing this.
Perhaps it was one some other branch somewhere that never made it into the new repo…

Hi gkkpch

Thanks for the reply.

The warning is simply an annoyance in scrolling output, but in mc I found the big red “error” was covering the dialogue where I had to confirm/select some action on files. It is a new installation, so I didn’t care if I made the wrong choice, but there is definitely some potential for breaking a working installation!

Looking more at the source of the issue, I am logging in with ssh and having my current locale used, which is en_GB.UTF-8, and this then is not available on the Volumio machine, hence the warning.

There is some more information in the following thread

I think it would be helpful to mention this issue in the Volumio docs about logging in with ssh, and also say how to stop the warning being printed if this should occur. I don’t think any changes are needed to Volumio itself.

We have a topic “Guides” in the Help section, I would say “go for it!” instead of waiting for someone else doing it

ashthespy · December 10, 2021, 1:08pm

Yes, this is done to save some space in the rootfs

+1 to what Gé said – could you also add a note here GitHub - volumio/volumio-developers-docs

EDIT: This would be exact file volumio-developers-docs/ssh.md at master · volumio/volumio-developers-docs · GitHub

Adrii · December 10, 2021, 2:46pm

Hi gkkpch

I don’t think a guide will help.

Adrian.

Adrii · December 10, 2021, 2:59pm

Hi ashthespy

Thanks for the suggestion. That is the page I thought the extra information should go. However, it would be easier for the dev team to add some text, if they want to include it, rather than for me to submit a PR which may well be ignored.

Adrian.

I completely understand your sentiments very well with long standing open PRs with Volumio, but this repo should go relatively quick!

Up to you in the end of course!
