+ date="2021-01-18T23:04:16Z"
+ content="""
+After setting up git-annex in one of my submodules, I noticed that executing `git checkout mybranch --recurse-submodules` will cause a fatal error (see error message below) and my working copy will be left in a state somewhere in between the origin and the destination branch.  
+As a workaround, this two-step alternative seems to work fine though: `git checkout mybranch && git submodule update`.  
+Everything above applies to command `git switch` as well.  
+I use git version 2.27.0 and git-annex version 8.20200618  
+
+Error Message: **fatal: could not open 'path/to/my/submodule/.git' for writing: Is a directory**
