ubuntu-minimal: please change Depends on isc-dhcp-client to dhcpcd-base

[Martin-Éric Racine]

ubuntu-minimal currently has a hard Depends on isc-dhcp-client. Unless there is a compelling reason to depend on a specific DHCP implementation, this should be changed to "isc-dhcp-client | dhcp-client" instead.

[Jeremy Bícha (jbicha)]

It is not possible for ubuntu-meta to use alternate dependencies, because ubuntu-meta relies on germinate.

[Martin-Éric Racine (q-funk)]

Could it Depends on dhcp-client and let APT decide which package providing this has the highest priority?

[Jeremy Bícha (jbicha)]

Only isc-dhcp-client is in Ubuntu Main and therefore is supported by Canonical.

Do you have a specific reason why people would need to use the alternate implementation?

[Martin-Éric Racine (q-funk)]

1) isc-dhcp-client doesn't do IPv6 well and cannot handle a dual-stack case at all.

2) isc-dhcp-client is EOL upstream.

3) https://bugs.launchpad.net/ubuntu/+source/dhcpcd5/+bug/2019191

[Jeremy Bícha (jbicha)]

Thank you for following up.

It looks like Ubuntu plans to switch ubuntu-minimal from isc-dhcp-client to dhcpcd-base for Ubuntu 23.10 already. There is no need to allow people to choose to install isc-dhcp-client instead at that point.

[Benjamin Drung (bdrung)]

Once we have dhcpcd in main (bug #2019191), initramfs-tools will switch to using it (bug #2024164). Then we should drop isc-dhcp-client from ubuntu-meta. The desktop will use network-manager and the server will use systemd-networkd.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubuntu-meta - 1.511
