Hi,

I found myself unable to edit a file using tramp on a given server.

After comparing with another server where it works I found the following:

> server where tramp works
> -rw-r--r-- 1 raf raf 675 nov.  13  2014 /home/raf/.profile
> server where tramp fails
> -rw-r--r-- 1 raf raf 675 Nov 13  2014 /home/raf/.profile

And then found that env (in a non-interactive ssh session) was
> LANG=fr_FR.UTF-8 # where it works
> LANG=en_US.UTF-8 # where it fails
(I didn't tried to understand how tramp could fail on the english string
parse the non-english output while failing at the apparently common one.

I could track down the difference to Debian's update-locale &
/etc/default/locale (it's another story).


My point is that  in order to make tramp more robust it should rather
set environment variables LANG/LC_* to neutral values for to maximize
chances of getting a predictable output (even if we still parse `ls` in 2016), 


thank you
(please keep me in CC:)

Per default, Tramp tries "en_US.utf8", "C.utf8", "en_US.UTF-8" in this
order. All of them shall be robust, I believe. See `tramp-get-remote-locale'.

Which Emacs/Tramp version are you using?

Best regards, Michael.

I overlooked it, thank you!

Emacs 24.4 from Debian Jessie
(tramp 2.2.9-24.4)

But it was not an issue with tramp (and I'm not sure what exactly where
the issue was)
But I finally got tramp, unchanged, to work on the various servers by
tweaking their default locale.

It's not quite clear what exactly was the server's side significant
change (among dpkg-reconfigure locales & update-locale).
I'd say that was an unknown edge-case.


but thank you for the answer!

Thanks for checking. I'm closing the bug.

Best regards, Michael.
