Drop the Microsoft apt repository in CI - #8
Merged
Conversation
The hosted runner image ships a packages.microsoft.com source that this build needs nothing from. Its InRelease fetch fails intermittently with E: Failed to fetch https://packages.microsoft.com/.../InRelease Clearsigned file isn't valid, got 'NOSPLIT' which aborts apt-get update and fails a single matrix job while every other PostgreSQL version passes. Remove any sources.list.d file naming that host before the first apt call, so setup only talks to the Ubuntu archive and PGDG. The step is a no-op if the image stops shipping the repository, and it stays exit-0 with or without pipefail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Problem
CI intermittently fails a single PostgreSQL matrix job during environment
setup, with nothing wrong in the change under test:
Seen on PR #6 (PG 17 job) and PR #7 (PG 12 job), both docs-only changes with
empty
regression.diffsand every other job green.Cause
The
ubuntu-24.04runner image ships apackages.microsoft.comentry in/etc/apt/sources.list.d. The firstsudo apt-get updatein the workflowfetches it, and a bad mirror response aborts the whole update. plruby installs
nothing from that repository.
Fix
Remove any
sources.list.dfile naming that host before the first apt call, sosetup only talks to the Ubuntu archive and PGDG.
The step is a no-op if the image stops shipping the repository, and stays exit-0
with or without
pipefail.🤖 Generated with Claude Code
