Sorry for the delay in the follow up test, it took me some time to get back to the system. > On 2020/01/26 13:56, Jason Pyeron wrote: > > I have an issue with git in Cygwin on windows shares - this is recent > > (worked months ago). > > > Just to be clear, you are running 'git' on Cygwin and not on linux > or some other OS? There is a 'git' that runs on window natively. Have Yes - Cygwin packaged git, as the cygcheck output indicated below. And indeed the files are on a \\server\share with a corresponding fstab entry. Cannot use other applications - not approved.
