Hello,
I have a problem on my LXC containers:
Code:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
  LANGUAGE = (unset),
  LC_ALL = (unset),
  LANG = "en_US.UTF-8"
  are supported and installed on your system.

Tried a bunch of things found on Google but none of them solved.

That was one of them and nothing... Tried to edit .bashrc too and nothing. I've been struggling with this for a while and only happened after moving to Proxmox 4 (clear install)

EDIT: That fixes me the problem on Ubuntu but not on Debian
 
What's the output of a simple `locale-gen` run (as root) without any extra parameters and what's in your /etc/locale.conf?

try running "dpkg-reconfigure locales" (as root) and select the appropriate locale(s).
 
I'm having same problem, with latest Proxmox, I configure locale via debian default locale configurator
Code:
dpkg-reconfigure locales
. But after I reboot container it goes back to how it was. And same perl and python errors appear.

I setup two locales en_US and lt_LT
 
please post the output of:
* `grep -v '^#' /etc/locale.gen`
* `set |grep -Ei 'lang|lc'`
run inside the container
 
This problem exist on an fresh pve install.

Code:
root@backup:~# uname  -a
Linux backup 4.15.18-12-pve #1 SMP PVE 4.15.18-35 (Wed, 13 Mar 2019 08:24:42 +0100) x86_64 GNU/Linux

pve-manager/5.3-11/d4907f84 (running kernel: 4.15.18-12-pve)
dpkg-reconfigure locales solves the problem. But i think it is a good idea that problem should fixed in a fresh installation. ;)

Reactions: japi
@fireon: are you accessing the fresh pve install via ssh from a session where you have a locale set (on your laptop/ssh-client), which is not configured on the pve server? - or are you accessing the node's console directly? (if yes - did you set a locale somewhere in your shell's rc files?)
 
the issue is still persistent on Debian 10, at least, but it is also an issue from the lxc image side, Proxmox is not responsible of these image, Proxmox only pull these image from LinuxContainer. It might worth it to discuss about this on their forum: https://discuss.linuxcontainers.org.

the only way I figure to fix this is by reinstalling locales in the LXContainer such as:

Bash:
apt install --reinstall --purge locales
dpkg-reconfigure locales
