FWIW, the fix in focal-proposed looks good on my end as well. I can confirm that the /etc/dhcp/dhclient-enter-hooks.d/resolved script now has the is-enabled check, and while I won't be able to test out resolvconf, I regard the updated conditional as equivalent to my previous known-good workaround (renaming the script to resolved.DISABLED, so it is not sourced by dhclient-script).

@thayne-u They don't care. There is ample reason to implement a fix for this, but they refuse to do what's best for users because they don't want us to run any software that doesn't start with "systemd". This is a very simple bug with a very simple fix, but they refuse to fix their defects. I've used Ubuntu as my primary OS since Warty Warthog. I've installed and supported it on countless desktop and server systems. Something changed in the culture a few years back -- they stopped listening to their users, around the time that Jono Bacon left. Now the community has no advocate to influence development.

[Bug 1853164] Re: systemd: /etc/dhcp/dhclient-enter-hooks.d/resolved error
For Ubuntu 20.04, resolvconf will not be allowed to manage /etc/resolv.conf, this will always be managed via systemd-resolved. So while you're right that this is a bug in the hook, it will not be a priority to fix since the code will be rewritten and replaced. > Alongside this, systemd's often-buggy resolver can be disabled. The vast majority of Ubuntu users are using systemd-resolved without incident or complaint. If you know of specific problems with it, we can best help you (and all other Ubuntu users) if you give us bug reports for those problems. ** Tags removed: rls-ff-incoming ** Tags added: rls-ff-notfixing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853164 Title: systemd: /etc/dhcp/dhclient-enter-hooks.d/resolved error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1853164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I thought we were going to some effort to reduce the number of systems where resolveconf was going to be used, or even remove it from the distro entirely.

[Bug 1853164] Re: systemd: /etc/dhcp/dhclient-enter-hooks.d/resolved error
Interesting. But the code is still incorrect, with my patch correcting it, so I guess we'll see how it goes. I can either fix it locally or go elsewhere, but I'm hoping it's simply fixed in the distribution.

sdezial notes this being terser.
