installed locales package post-installation script subprocess was killed by signal (Bus error)

The postinst script of the locale package fails. Not sure what this "Bus error" signal means. It fails as well when you run the configuration step manually?

dpkg --configure locales

If so, can you run this:

bash -x /var/lib/dpkg/info/locales.postinst configure

[SMillerDev]

No dice on the first one:

root@DietPi:~# dpkg --configure locales
Setting up locales (2.31-13+rpt2+rpi1+deb11u7) ...
dpkg: error processing package locales (--configure):
 installed locales package post-installation script subprocess was killed by signal (Bus error)
Errors were encountered while processing:
 locales

And the second is not showing any more info either:

root@DietPi:~# bash -x /var/lib/dpkg/info/locales.postinst configure
+ set -e
+ LG=/etc/locale.gen
+ EE=/etc/default/locale
+ LC_ALL=C
+ LANG=C
+ '[' configure = configure ']'
+ . /usr/share/debconf/confmodule
++ '[' '!' '' ']'
++ PERL_DL_NONLAZY=1
++ export PERL_DL_NONLAZY
++ '[' '' ']'
++ exec /usr/share/debconf/frontend /var/lib/dpkg/info/locales.postinst configure
Bus error

[MichaIng]

It is the debconf frontend call which fails. Since we force noninteractive, it is the perl script itself or perl-base. Try to reinstall those two packages:

apt install --reinstall debconf perl-base

That seems to have worked, thanks a ton @MichaIng !
