Code-server: Binary does not work with WSL

[DiegoBM]

• vscode-remote version: 1.31.0-20
• OS Version: Windows 10 (rel 1809) - WSL Ubuntu 16.04.4 LTS

Steps to Reproduce

1. Run WSL and try to run the executable
2. Error: -bash: ./code-server: cannot execute binary file: Exec format error

Will look into this. Thanks for the report.

[nikeinikei]

can confirm, didn't work for me either, with same error message

[kylecarbs]

Seems like binaries compressed with UPX do not work in WSL.

We'll create a version in the CI that isn't compressed. You can try decompressing it, might work.

@kylecarbs running the upx -d command on the binary it says that the binary was not packed by upx

# upx -d code-server

Ah interesting. We compress the node binary prior to packaging, so that
makes sense. Will add the additional target soon.

Running from docker on WSL would be good. Right now I use Cloud9 local install through https://github.com/c9/core for Python development. Wonder if Coder can provide better intellisense.

Any chance to disable that UPX compression in the next release?

The plan was to add an additional target and not remove an optimization.

@SuperSandro2000 who's saying otherwise? It was already mentioned by @kylecarbs that it would be an additional target

[code-asher]

We ended up skipping compression altogether (from 1.32.0-245 onward): https://github.com/codercom/code-server/commit/8bab787804912306821e50747699ce25ba1d22e9.

[DiegoBM]

@coderasher, was compression causing other unexpected problems? Out of curiosity

[DiegoBM]

Now it works flawlessly on WSL, thank you! Closing as fixed
