The syntax on line 16 and elsewhere, i.e. `if [[ -t 1 ]]; then` doesn't work in sh - it's a bash feature. Tested on Ubuntu 25.10. The current install script errors with: ``` ./install.sh: 16: [[: not found ./install.sh: 50: [[: not found ./install.sh: 69: [[: not found #=O#- # # curl: (22) The requested URL returned error: 404 ``` Changing to `#!/bin/bash` solves the problem. It was probably working in many places because some systems symlink /bin/sh to /bin/bash.

I don't think that's enough, as in docs curl piped to sh. Why not convert the script to posix instead? LLMs are good at that. |

D'oh, good point. Opened a separate PR to update the docs: DioxusLabs/docsite#594
Rewriting it to be POSIX shell compatible is a good idea if it truly needs to run under /bin/sh, and maybe we'd get lucky asking an LLM to do it, but I'm not familiar enough with POSIX shell scripting to confidently review the LLM's output. If updating to bash is undesirable, that's OK, I can withdraw these PRs or you can close them. |
