@DarkPark @baryluk what's the recommended course of action here?

I saw you made this diagram: #1248 (comment)

[baryluk]

@DarkPark Could you try musl version. My guess is it is statically linked, and maybe it will work.

As far as I know the only reasonable option is to build on older version of Ubuntu or Debian, so minimal GLIBC ABI used is lower than 2.34. glibc does not support other methods.

@baryluk Installing git-delta-musl_0.15.1_amd64.deb works just fine, because the generated control file doesn't show any dependencies on libc6 (>= 2.34). I think this could be a temporary workaround.

@dandavison A possible way to address this would be to build delta on a debian image instead of ubuntu-latest (I think) so the dynamic reference uses an older version of glibc. Alternatively, musl could just become the default package.

Same here. Broken install in debian:bullseye docker image, that I use in my VScode devcontainer setup. I don't need any fancy modern OSs.

#4 122.6 The following packages have unmet dependencies:
#4 122.6  git-delta : Depends: libc6 (>= 2.34) but 2.31-13+deb11u5 is installed

musl version works

@MarcoIeni do you have any thoughts on the right way forwards here?

GitHub doesn't offer a Debian image :/
See this

Alternatively, musl could just become the default package.

Yes, we can remove git-delta_0.x.y_amd64.deb from the releases and make git-delta-musl_0.x.y_amd64.deb the default (by renaming it to git-delta_0.x.y_amd64.deb)

[eggbean]

Wouldn't just using the ubuntu 20.04 GitHub Actions runner work? Ubuntu 20.04 uses glibc 2.31. I can't use the latest version of delta on Debian instances, so I have switched to the musl build for the time being.

I've just installed on Ubuntu 20.04.5 LTS and got the same error:

❯ sudo dpkg -i git-delta_0.15.1_amd64.deb

It gets installed but fails:

delta: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by delta)
delta: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by delta)

I tried building it from source but got errors:

Any idea of how to get it running?

Perhaps a docker image version?

Followup:

I could install version 0.14.0 and it works:
