Running dotnet-install.sh from MINGW64 is not supported #715
Description
Activity
Root cause
src/dotnet-install.shonly recognizes theseunamevalues inget_current_os_name():Darwin→osxFreeBSD→freebsdLinux→linux/linux-musl/rhel.6
In Git Bash / MSYS2 / MINGW64,
unamereturns something like:MINGW64_NT-10.0-26200That falls through to the error path:
say_err "OS name could not be detected: UName = $uname" return 1
So the reported failure is consistent with the current script behavior.
Relevant code
get_current_os_name() { eval $invocation local uname=$(uname) if [ "$uname" = "Darwin" ]; then echo "osx" return 0 elif [ "$uname" = "FreeBSD" ]; then echo "freebsd" return 0 elif [ "$uname" = "Linux" ]; then local linux_platform_name="" linux_platform_name="$(get_linux_platform_name)" || true if [ "$linux_platform_name" = "rhel.6" ]; then echo $linux_platform_name return 0 elif is_musl_based_distro; then echo "linux-musl" return 0 elif [ "$linux_platform_name" = "linux-musl" ]; then echo "linux-musl" return 0 else echo "linux" return 0 fi fi say_err "OS name could not be detected: UName = $uname" return 1 }
What I checked
- Verified the current
get_current_os_name()logic insrc/dotnet-install.sh - Confirmed that
MINGW64_*is not handled there - Searched the repo for any existing
MINGW64handling and did not find any
Assessment
At minimum, this is a real OS-detection gap for Git Bash / MINGW64.
The open question is whether the script is intended to support that environment. If yes, then this should be fixed by adding handling for
MINGW*/MSYS*/ possiblyCYGWIN*and mapping appropriately to artifact behavior.Suggested next step
I think the next step is deciding between:
-
Support Git Bash explicitly
- detect
MINGW*/MSYS*/ possiblyCYGWIN* - map to the correct Windows OS identifier
- verify downstream behavior such as archive type, executable naming, and path handling
- detect
-
Document it as unsupported/do nothing
- replace this with a more actionable error telling users to use PowerShell, CMD, or WSL instead
More than just supporting the windows OS in the shell script, we'd also need to extend the shell script to support getting the WindowsDesktop runtime - it currently doesn't do that because it was only ever intended for non-Windows platforms.

Based on the context @baronfel provided and the fact that these scripts are in maintenance mode, I'm closing this as an unsupported scenario.
From within git bash / MINGW64 bash, I ran
curl https://builds.dotnet.microsoft.com/dotnet/scripts/v1/dotnet-install.sh | bashand got this error:I'd expect this to just work^(tm)
Thanks!
