Thread blocked in an STM transaction

[Proximyst]

Hi, I'm an Arch user (relevant neofetch + glibc? https://owo.whats-th.is/5zu65ff.png) and I've installed cabal using the bootstrap script. I then used cabal to install stack, and stack is now trying to install HIE. However, when it gets around to unpacking ghc-tinfo6-8.6.4 (and once even got that and went on to installing but failed with the same error), it errs with thread blocked indefinitely in an STM transaction and error code 1. This is done with stack install.hs. It always manages to download ghc-tinfo6, but it never manages to actually use it.
I'm new to Haskell as a whole and for sure don't know much about the ecosystem, so I might be missing something but I'm fairly sure I've been doing it correctly so far.

could you try to run stack build --stack-yaml stack-8.6.4.yaml manually?

[fendor]

Does a normal stack project work? E.g.execute stack new test, will create a test directory with a project. Can you then try to use stack build in the newly created directory? I think this error is stack and arch related.
Also, does stack setup succeed?

Last but not least, welcome to haskell!

I just ran into this on Arch Linux 5.1.16:

This seems to be a problem with stack. Could you try running stack setup anywhere?

[mb720]

stack setup in a directory with a Stack project produces

stack will use a sandboxed GHC it installed
For more information on paths, see 'stack path' and 'stack exec env'
To use this GHC and packages outside of a project, consider using:
stack ghc, stack ghci, stack runghc, or stack exec

stack setup outside a Stack project:

Writing implicit global project config file to: /home/mb/.stack/global-project/stack.yaml
Note: You can change the snapshot via the resolver field there.
Using latest snapshot resolver: lts-13.27
stack will use a sandboxed GHC it installed
For more information on paths, see 'stack path' and 'stack exec env'
To use this GHC and packages outside of a project, consider using:
stack ghc, stack ghci, stack runghc, or stack exec

[fendor]

This seems like a problem with stack, maybe somebody reported this upstream already. Can you try to manually invoke stack install.hs hie-8.2.2 and stack install.hs hie-8.6.5?

[mb720]

Thanks for your quick responses. Where can I find install.hs?

[jneira]

@mb720 the path where aura downloaded the haskell-ide-engine seems to be /var/cache/pacman/pkg/haskell-ide-engine2770/haskell-ide-engine/src/haskell-ide-engine-0.10.0.0 so the install.hs script should be there

[fendor]

Or clone this repo and execute the command in the top level of this repo

[mb720]

Thanks @jneira. aura did not keep the code in /var/cache/pacman/pkg/.

I cloned the repo and ran

stack install.hs hie-8.2.2

which resulted in

Unpacking GHC into /home/mb/.stack/programs/x86_64-linux/ghc-tinfo6-8.6.4.temp/ ...
thread blocked indefinitely in an STM transaction

On the other hand, judging from the output of

stack install.hs hie-8.6.5

it built and configured all kinds of packages (e.g., network-uri-2.6.1.0, async-2.2.1). The last messages are

Stack version:

Version 1.9.3.1, Git revision 43ff632b030f50898bff793c9e6c634637ba6001 (6217 commits) x86_6

[fendor]

So, this is a problem upstream, that stack fails to install ghc-8.2.2 on arch linux.
