[ChieftainY2k]

I'm getting an error when creating a new sync, followed instructions closely, installed mutagen-agents.tar.gz along with mutagen.exe

Alpha is Win11 x64
Beta is Ubuntu 22.04.5 LTS (VM)

Alpha:

mutagen version
> 0.17.6

$ ssh -V
OpenSSH_9.8p1, OpenSSL 3.0.15 3 Sep 2024

Beta:

ssh -V
OpenSSH_8.2p1 Ubuntu-4ubuntu0.11, OpenSSL 1.1.1f  31 Mar 2020

Command:

mutagen sync create --name="code" "c:\code\" "user@host:2224:/code
Probing endpoint (POSIX)...
(...getting stuck until timeout.)

"Probing endpoint (POSIX)..." Started happening for me with OpenSSH_9.9p1. Before that I was with 9.8p1 and it worked without issues.

Seems related to git-for-windows/git#5199
An update of git for windows had some bug in msys-2.0.dll.
Restoring msys-2.0.dll from a previous version of git-for-windows did the trick for me.
Just a quick note: don't mv msys-2.0.dll msys-2.0.old.dll from a git bash, for reasons that quickly became obvious 😅

Thanks for identifying the solution @jeremyVignelles, that's a huge help. I'll close this for now then since there's a fix available and it's an upstream issue.

[jeremyVignelles]

Well, shout out to @kanevbg which put me on the right tracks by identifying the culprit. I just came two days later when the issue was already opened on the git for windows repo, with a workaround available 😉

Unlikely in my case, as I don't use git for windows.
I'm using newest cygwin for Windows, with the latest updates.
The git version is 2.45.1 , and there's no such file as msys-2.0.dll in my filesystem.
