perl: warning: Setting locale failed.

#1

running some programs will give this result , this is happened with different applications one of them vrms will give this issue:

user@host:~$ vrms
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "",
        LC_ALL = (unset),
        LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

No non-free or contrib packages installed on host!  rms would be proud.
user@host:~$

something needs to be installed ? or we just ignore it?

#2

Not a bug by default in Whonix. Comes from some custom configuration
applied by user. Therefore should be sorted out as per
https://www.whonix.org/wiki/Free_Support_Principle.

#3

vrms is installed by default , not customization i have done.

or you mean the tool vrms itself needs user customization?

this is another example but while installing a tool outside whonix:

#5

Can’t reproduce.

#6

I did get the locale settings with programs run from terminal, including apt-xxx.
Could not find out the cause, so I just reconfigured locales in the templates (happening in Whonix only). .

sudo dpkg-reconfigure locales

and choose en_US.UTF-8, which should be the default after a fresh installation.

#7

or as i saw in debian-9 inside qubes , it install “locales-all” which we miss inside whonix. normal installation sudo apt install locales-all will break whonix, needs further modification to be implemented.

#8

TNT BOM BOM:

or as i saw in debian-9 inside qubes , it install “locales-all” which we miss inside whonix. normal

I am not convinced its required.

installation sudo apt install locales-all will break whonix,

Please elaborate what you mean by “breaks Whonix”?

#9

i meant it will suggest to remove everything:

user@host:~$ sudo apt install locales-all

Worth investigating.

Strange. You seem to have qubes-whonix-workstation installed. Good.

Try.

(I still don’t think we need locales-all installed. But this packaging issue is worth finding out.)

Try please:

sudo apt-get install locales-all qubes-whonix-workstation

Don’t proceed. Copy output here.

qubes-whonix-workstation is already the newest version (3:7.9-1).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libc6 : Breaks: locales-all (< 2.27) but 2.24-11+deb9u3 is to be installed
 qubes-whonix-workstation : Depends: qubes-whonix-workstation-packages-recommended but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
