[Bug]: ssh provider workspace doesn't start when zsh is the default user shell #1621
Description
Before submitting
- I have searched existing issues to confirm this is not a duplicate
- I am running the latest version of Devsy
What happened?
I'm trying to run devsy via ssh provider on one of my servers whose user has default shell zsh
Running into:
ERROR main:7: command not found: sh -cOnce I have chsh -s /bin/bash on the remote server, it works again.
What did you expect to happen instead?
Launch my editor upon successful copy
Steps to reproduce
- setup remote server with zsh as default shell:
chsh -s /bin/zsh - Add ssh provider:
devsy provider add ssh --name server -o HOST=user@server - Try to launch a workspace:
devsy workspace --provider server .
devcontainer.json
