It even works on win10 linux subsystem. But on Cygwin, only the local tests work, but the remote tests (which need the pictured ssh pipe) fail or hang. When trying to find out what's going wrong, I noticed corrupted data coming over the pipe. I've found some other pipe issues on the cygwin mailing list, maybe this is related? Our issue about this: https://github.com/borgbackup/borg/issues/1268 Note: I am one of the borgbackup developers, but I am not a windows developer (and I personally don't use windows or cygwin except for testing borgbackup on this platform). What I could offer is to run the tests on a fixed version.
