The Internet Systems Consortium has stopped maintaining their DHCP client, which is standard on a lot of distros.
Debian has updated its documentation and now warns users to choose an alternative:
https://packages.debian.org/bookworm/isc-dhcp-client
On Debian Unstable, I was already forced to uninstall it in yesterday’s upgrade.
If you’re using network-manager, you don’t need to worry, since it includes its own dhcp client, but for others, this might be relevant.
On Arch, this concerns the dhcpd package:
https://wiki.archlinux.org/title/Dhcpd
When I updated Debian Unstable 2 days ago, it forced me to uninstall isc-dhcp-client in order to upgrade network-manager.
So I looked up the reason and found the ISC’s blog post. I shared it here thinking it might be interesting to some, since Debian’s packages are the basis for a lot of other distros that might be affected soon.
Okay, fair point, so it is relevant for a current issue
