I couldn't reproduce the issue with your command workflow.
The only difference I see, is that I was using:
dvc add ssh://sshcache/incident_old.csv
and
in your workflow it is:
dvc add remote://sshcache/incident_old.csv

I guess the doc is misleading on that point

It says :

#Add data on SSH directly
$ dvc add ssh://user@example.com:/mydata

@thomasryck , thanks for the notice!

The problem here is that when you are using the ssh syntax you need to provide everything on the URI (user, port, etc.), however, with remote:// the configuration it is going to be fetched from such remote.

(cc: @jorgeorpinel maybe is worth to open an issue about this on the docs 🤔 )

Did I capture the issue correctly? treeverse/dvc.org#411

I am getting this error while running the dvc add ssh://sshcache/car.txt
