Hi, I tried to see what actually happened in the test cases. I seem to have boiled things down to the following line, when evaluated, tramp hangs. When enabling debug-on-quit, I get the attached backtrace after hitting C-g. (write-region "test" nil "/mock:anders-lindgrens-macbook.local:/private/var/folders/qq/qqGPPGoBHOGgJs3oBoKTHU+++TI/-Tmp-/tramp-test1900-Fy/test") The directory exists and is empty. It looks like the code tries to run an external command "mock" (which doesn't exits, as far as I know). -- Anders On Wed, Dec 16, 2015 at 11:39 PM, Michael Albinus wrote: > Anders Lindgren writes: > > > Hi, > > Hi Anders, > > > Unfortunately, it still hangs. > > I'm running out of ideas.
