Erlang security update breaks guam on Debian 10

[Lennart]

Hello,

For those on Debian 10: a security update for erlang-base replaces 
erts-10.2.4 with erts-10.6.4. This breaks guam.

See https://lists.debian.org/debian-lts-announce/2023/07/msg00012.html

Hopefully the kolab package maintainers can update guam.

For now, I downgraded to the previous erlang packages on my system. This 
might pose a security risk!

apt install erlang-base=1:21.2.6+dfsg-1 erlang-asn1=1:21.2.6+dfsg-1 
erlang-crypto=1:21.2.6+dfsg-1 erlang-ftp=1:21.2.6+dfsg-1 
erlang-inets=1:21.2.6+dfsg-1 erlang-mnesia=1:21.2.6+dfsg-1 
erlang-public-key=1:21.2.6+dfsg-1 erlang-runtime-tools=1:21.2.6+dfsg-1 
erlang-ssl=1:21.2.6+dfsg-1 erlang-tftp=1:21.2.6+dfsg-1 
erlang-syntax-tools=1:21.2.6+dfsg-1 && apt-mark hold erlang-base

Best wishes,
