+I am trying to use git-annex as part of a datalad install on an Ubuntu 18.04 VirtualBox VM to set up a repository linking to some datasets at a public ftp server.  When I use git-annex version 7.20190219 (installed with apt-get install git-annex-standalone from NeuroDebian) to add the links, I get the following error:

+However when I use git-annex v 6.20180227 (installed from the apt repository that came with Ubuntu 18.04) the link is generated correctly:

+Similarly, after publishing the correctly formed links generated with 6.20180227 to github, trying to download them on another Ubuntu VirtualBox VM with git-annex 7.20190219 installed causes the following error:

+Would you know why this is happening?  And how I can avoid this failure mode in the more up-to-date version of git-annex?
