Instalation issue on ubuntu

[amitguptagwl]

I'm getting the error on first step ie Setup repository

Err:8 https://dist.crystal-lang.org/apt crystal InRelease

Do you use 18.04? When I try to install Crystal with 18.04, I get this error too and I also had other issues installing packages. You should try 16.04. For me the most stuff works in 16.04.

No! I'm using 17.10. I tried to follow manual steps but facing issue in that

Unpacking crystal (0.27.0-1) ...

@amitguptagwl So the first error came from running the setup script https://dist.crystal-lang.org/apt/setup.sh? Unfortunately that one's different from the manual steps in that it refers to a key hosted on keys.gnupg.net which has already caused some issues. Not sure if that's related.

The second error looks like a hiccup in the apt installer. It seems that the key validation has succeeded at least.
Try apt purge crystal && apt install crystal to reinstall the package.

I've also tried chmod +655

Any insight on what might be causing this error in /usr/share/doc/crystal/api? I'd like to think this is some apt/dpkg issue and not necessarily caused by the Crystal package. Might be wrong though.

FYI you can also install the binary directly without apt: https://crystal-lang.org/docs/installation/from_a_targz.html

It's your antivirus. Don't use antivirus solutions, especially on linux.

i just setup a new wsl instance and am unable to install crystal on it;

Manually adding the key also doesnt works;

[straight-shoota]

This seems to be a gpg issue. Which gpg package are you using? Maybe this can help: https://stackoverflow.com/questions/46673717/gpg-cant-connect-to-the-agent-ipc-connect-call-failed

After some investigation, I think this is the issue; microsoft/WSL#5125
I installed ubuntu 20.04 on wsl1 which is not supported.
I will try to get on wsl2 tomorrow and see if everything works fine there
