perl: warning: Setting locale failed.

I got below mentioned message since I have installed Kubuntu about 3 years ago:

perl: warning: Please check that your locale settings:
LANGUAGE = "",
LC_ALL = (unset),
LC_TIME = "de_AT.UTF-8",
LC_MONETARY = "de_AT.UTF-8",
LC_CTYPE = "C.UTF-8",
LC_ADDRESS = "de_AT.UTF-8",
LC_TELEPHONE = "de_AT.UTF-8",
LC_NAME = "de_AT.UTF-8",
LC_MEASUREMENT = "de_AT.UTF-8",
LC_IDENTIFICATION = "de_AT.UTF-8",
LC_NUMERIC = "de_AT.UTF-8",
LC_PAPER = "de_AT.UTF-8",
LANG = "en_AT.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
perl: warning: Setting locale failed.

How can that be fixed?

Also weird is that under /etc/default/locale it says that the Language is en_US.UTF-8 thus I do not get why it says in the error that language = nothing set.

LC_ALL is missing but what should that be set to?

• LC_ALL is normally unset; it can be used as an override for all the others
• "Falling back to the standard locale ("C") ... No such file or directory" suggests the file /usr/share/i18n/locales/C is not there. Can you check whether the directory exists, and has hundreds of files (including de_AT)? If it does, maybe the environment variable LOCPATH is set? If the directory is missing, apt-file search tells me that the locales package has it.
• running locale in a konsole might be informative, as might locale -a

I suspect you've got some environment variables related to locales badly set. I suggest running env in a konsole and reviewing them.

It is there, C is a file though.
de_AT is in the locales folder

I guess this is void now because Kubuntu does not start anymore after the update to 24.4 thus I cannot try console commands.

Seems my bad feeling about that update was right, I shouldnt have done it :/
