Hi @mathias3 . Could you please upgrade to the latest version (1.1.7 as of right now) and try again?

Hi @mathias3 . Could you please upgrade to the latest version (1.1.7 as of right now) and try again?

sudo apt-get install --only-upgrade dvc
returns
dvc is already the newest version (1.0.1).

I am installing from deb directllu from github then

[efiop]

@mathias3 I think you need to sudo apt update first. I can confirm that 1.1.7 is in our deb repo already.

When  I use push pull  add remote- in one repo 'tutorial like' everything works fine. but when I try to use it as a "data repository" fucntion , and then use get-url  like described this happens and kills whole functionality

@mathias3 Thanks! Indeed, it is a known bug when trying to get-url a directory. #4144 For now, you could just use scp or rsync with the same effect.

I'll close this issue as a duplicate of #4144. Thank you for the feedback!
