New Debian lxc with problems

[.n3]

Hey,

I downloaded the debian 13 template and created a new lxc with this template. I used the default features and disabled nesting.

First I have the problem, that I do not see console. It shows a black screen. Through the shell I can connect to the container. I updated and upgraded the container but I get errors adding a user and the console still show a black screen. I'm confiused, because it is a fresh installation:

root@database:~# adduser db_user
perl: warning: Setting locale failed.

        LANGUAGE = (unset),

        LC_COLLATE = (unset),
        LC_TIME = (unset),
        LC_MESSAGES = (unset),

        LC_NAME = (unset),
        LANG = "en_US.UTF-8"
    are supported and installed on your system.

I used the default features and disabled nesting.

Nesting is required by newer templates, like Debian 13, because of the newer systemd version. That's the main reason that it's on by default nowadays. Lots of threads on this forum about this.

perl: warning: Setting locale failed.

The locale issue is on every template and you can use dpkg-reconfigure locales to set a locale.

logger: socket /dev/log: Connection refused

I don't know about this one, sorry, Maybe enable (the default) nesting to see if the problem goes away?

It was the nesting. I deleted the lxc and created a new one with nesting but the problem still exists. I don't know how, but nesting was again disabeld. To thrid lxc with nesting is working. Thanks! Also thank you for the reconfig of the locals. Add this to my Howto ;-)

Also, it is a good idea to do a dpkg-reconfigure tzdata so that the Timezone is also set.

Thanks for the hint. therefor I use timedatectl set-timezone Europe/Berlin

Should I also execute:

systemctl stop sys-kernel-config.mount
systemctl mask sys-kernel-config.mount

Yes, sometimes container templates have some services that don't make sense and/or cannot work in an unprivileged context.

I have some docs about this here but the TLDR is to run dpkg-reconfigure locales and reboot or log in again.
Oh, it was actually answered already. Maybe the link is still helpful.
