Public bug reported: I use Ubuntu via Github CI. When I have ports.ubuntu.com included in my sources (to gain access to some extra architectures via multiarch and emulation), I fairly often encounter errors that look like this:
Err:12 https://ports.ubuntu.com noble-updates/main ppc64el Packages File has unexpected size (726424 != 721256). Mirror sync in progress?

That was a few weeks ago; I just tried enabling these jobs again and I am still (or again) seeing this error. This happens with the archives for ppc64el and s390x. Having "apt update" fail for hours or even days every few weeks makes these archives largely unusable for CI (during every one of these outages, we'd be unable to test or land any changes in our repo). I have never encountered this issue for more mainstream architectures like amd64 and aarch64, so apparently it is possible to run Ubuntu archives in a way that avoids this issue. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2130309 Title: "apt update" often fails for ports.ubuntu.com (ppc64el, s390x) with "Mirror sync in progress?"
