Error when building Docker image

[deavmi]

Trying to build the image with sudo docker build yet I am running into this error:

 => ERROR [simplex_xftp build  4/16] RUN ghcup set ghc "9.6.3" &&     ghcup set cabal "3.12.1.0"                                              1.0s

Any help will be much appreciated.

Error seems to be that ghcup is not being installed.

Hello there.

Not sure, following the exact steps in README.md works fine on my end (and in Github CI, for that matter).

Do you have another machine with Docker to reproduce?

Found the issue: haskell/ghcup-www#10

---

That took me some time to find as the piped command failed without stopping the build, yet continued and then obviously no ghcup binaries were to be found.

My current work-around is to host that script locally on my web server, but I am hoping the ghcup team get their stuff together and fix it (as mentioned in that error).

[deavmi]

I am going to test build now and then report back...

[shumvgolove]

That's interesting. Thanks for the heads-up.

[deavmi]

It is progressing... will keep everyone updated.

[deavmi]

That's interesting. Thanks for the heads-up.

No problemo! Also it looks like my build has worked. I made this little fix (personal fix, don't expect anyone to use it but will reference it in my fork: https://github.com/deavmi/simplexmq/blob/stable/Dockerfile#L21)

[deavmi]

Going to close this now as I have a workaround. As for the ghcup - it seems they won't be able to fix it due to their (drum roll 🥁 ) Cee-dee-en (read CDN).

See: haskell/ghcup-www#10 (comment)
