snapcraft (edge) fails to build core24 snaps. Running "apt update" within base container fails
Metadata
Current evaluation
snapcraft edge fails to build core24 snaps due to apt update failing with unresolved ftpmaster.internal in base container. Issue is 931 days old with no maintainer response.
Suggested action: close stale
Reason: The issue is 931 days old with no maintainer engagement and concerns an old edge version (8.0.3.post24+git23d55913) that is no longer current. Evidence from craft-providers commit history shows related fixes: 'remotes: use released images for noble and oracular (#735)' and 'fix: do not update apt sources for devel images (#504)' which likely addressed the ftpmaster.internal resolution problem by switching to released images instead of devel images with internal mirror references.

Issue body
This issue does NOT occur on current latest/stable which is "8.0.3". It happens on latest/edge (8.0.3.post24+git23d55913).
When building core24 based snaps I get following error:
# snapcraft pack
Running snapcraft with a devel instance is for testing purposes only.

Commit dd365bf changed noble image handling to use released images instead of devel images, which would eliminate the ftpmaster.internal mirror dependency that caused this error.
