We’re seeing the same issue as reported by gward-tridium with Snapcraft v7.2.4.
Let me know if there’s anything we can do to help debug.
@andrewsomething, I have a fix here, would you be able to test it using channel=edge/pr-3971?
@mr_cal I can confirm that resolves the issue for me. Thanks for the quick work!
@mr_cal The fix on edge/pr-3971 fixes our issues as well. Thanks for taking a look!
Great! Thank you @gward-tridium, @andrewsomething, and @jocado for the good feedback and testing. This fix is now released to the channel latest/candidate
Great - thank you for your support 
Just used channel latest/candidate, but still have the issue ‘“http://localhost/v2/snapctl”: dial unix /run/snapd-snap.socket: connect: no such file or directory’

Was I too soon in using latest/candidate?
Ah wait, might be caused by me using jammy as UBUNTU arg?
UBUNTU=Jammy is not the problem. From your logs, the first call to snapctl works but the second does not. Curious behavior, I can’t reproduce that or figure out how it happened.
Regardless, the fix is simple and I’ll have prepared today.
Can you provide some details on how you are doing setup, execution, or provide the snapcraft.yaml? It looks like a core22 snap being built non-interactively. I’d like to write regression tests to not break docker builds again.
Update 1: PR is here and can be tested on channel edge/pr-3974
Update 2: Released as version 7.2.7 and should be available on the channel candidate soon
I will test it asap. I did adapt the Dockerfile as well, added core22 to it.

I did adapt the dockerfile, and added core22 to it
Thanks @hardeves94! Your subsequent error should be fixed shortly with https://github.com/snapcore/snapcraft/pull/3982.
P.S. You can add code blocks by adding a line with 3 backticks (`) before and after the code.
Thanks @mr_cal, I will test it next week. And thanks for the hint 
Sorry, it took a while longer, sometimes deadlines can be a real pain. I tried with channel=candidate, but unfortunately, now a different error occurred: It tries to install lxd into the docker image, and it fails to do this:
