W: Setting locale failed
WARNING: Setting locale failed
The error message
If you are getting inexplicable locale warnings when performing upgrades, such as:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_TIME = "en_GB.UTF-8",
LC_MONETARY = "en_GB.UTF-8",
LC_ADDRESS = "en_GB.UTF-8",
LC_TELEPHONE = "en_GB.UTF-8",
LC_NAME = "en_GB.UTF-8",
LC_MEASUREMENT = "en_GB.UTF-8",
LC_IDENTIFICATION = "en_GB.UTF-8",
LC_NUMERIC = "en_GB.UTF-8",
LC_PAPER = "en_GB.UTF-8",
LANG = "en_US.UTF-8"The cause
If you are connected over SSH, consider what locale you are passing over with your client.
This can be seen with e.g. ssh -v root@node as:
debug1: channel 0: setting env LC_ADDRESS = "en_GB.UTF-8"
debug1: channel 0: setting env LC_NAME = "en_GB.UTF-8"
debug1: channel 0: setting env LC_MONETARY = "en_GB.UTF-8"
debug1: channel 0: setting env LANG = "en_US.UTF-8"
debug1: channel 0: setting env LC_PAPER = "en_GB.UTF-8"
debug1: channel 0: setting env LC_IDENTIFICATION = "en_GB.UTF-8"
debug1: channel 0: setting env LC_TELEPHONE = "en_GB.UTF-8"
debug1: channel 0: setting env LC_MEASUREMENT = "en_GB.UTF-8"
debug1: channel 0: setting env LC_TIME = "en_GB.UTF-8"
debug1: channel 0: setting env LC_NUMERIC = "en_GB.UTF-8"Since PVE is a server, this would be best prevented on the nodes by taking out:
AcceptEnv LANG LC_*from /etc/ssh/sshd_config. 1
Alternatively, you can set your locale in ~/.bashrc, 2 such as:
export LC_ALL=C.UTF-8Notes
If you actually miss a locale, you can add it with:
dpkg-reconfigure localesAnd generate them with: 3
locale-gen
