sbtn 1.8.1 regression on Debian 11 with glibc 2.31

[Locke]

steps

I just updated sbt on two Debian 11 ("bullseye" / "stable") x86_64 machines from 1.8.0 to 1.8.1 (a local machine and a vm used for GitHub Actions hosted-runner).

problem

On both I can no longer start sbtn and receive the following output instead.
This happens not only in a project folder which I compiled successfully just before the update, but also in a completely empty folder.
It happens with both sbt --client and manually downloaded sbtn.

ci@vm03:/tmp/foo$ sbt --client clean

expectation

sbt and sbtn should work on Debian 11 ("bullseye" / "stable") with glibc 2.31, as this is the current supported release.
Otherwise, it has to be clearly stated somewhere (e.g. https://www.scala-sbt.org/download.html), that systems with an older glibc like Debian 11 are no longer supported.

other systems

I manually downloaded sbt from the GitHub Release onto Debian 12 ("bookworm" / "testing", using glibc 2.36-7) on my RaspberryPI 4 (aarch64) and had no problem with the simple clean smoketest.

@Locke Thanks for the detailed report!

I guess this could be caused by ipcsocket build (https://github.com/sbt/ipcsocket) or the GraalVM native-image build for sbtn. In general, any part of the sbt that requires native integration is somewhat finicky, and if the compatibility is not enforced by CI (often set to "ubuntu-latest") we won't notice when it slips.

@mkurz Do you know if this is mostly due to whatever the glibc lying around in the Github Actions image we use to build sbtn? If so using slightly older ubuntu would restore the Debian 11 compatibility?

[eed3si9n]

https://repology.org/project/glibc/versions says Ubuntu 22.04 uses glibc 2.35, and Ubuntu 20.04 uses glibc 2.31. I'd be happy to try to downgrade the Ubuntu machine and see if this might get fixed.

I am pretty sure that should fix the problem. You used ubuntu-latest to build sbtn 1.7.0 in July 2022, so back then effectively ubuntu-20.04 was used. Since beginning of November 2022 however ubuntu-latest points to ubuntu-22.04: https://github.blog/changelog/2022-11-09-github-actions-ubuntu-latest-workflows-will-use-ubuntu-22-04/

[eed3si9n]

Thankfully this was fairly easy to reproduce on Github Actions as well using ubuntu-20.04 - #7119

[mkurz]

👍 IMHO that bug basically was more or less unavoidable, and it was just waiting till a new ipcsocket release gets cut 😉 Guess we stay on ubuntu 20.04 for a bit longer.
