@dorp92 please share the contents of your .dvc/config file if possible to see what your default remote is. Can you also share the output of dvc version?

[dorp92]

DVC version: 1.10.2 (deb)
---------------------------------
Platform: Python 3.7.9 on Linux-5.4.0-56-generic-x86_64-with-debian-buster-sid
Supports: All remotes
Cache types: hardlink, symlink
Cache directory: ext4 on /dev/nvme0n1p2
Caches: local
Remotes: None
Workspace directory: ext4 on /dev/nvme0n1p2
Repo: dvc, git

There is no .dvc/config

[jorgeorpinel]

There is no .dvc/config

That's strange. How did you configure your remotes, did you use the --local, --global, or --system flags of dvc remote add/modify?

If you don't know please just show the output of dvc remote list as well as of dvc remote default.

In general, it's difficult to troubleshoot this with the very short messages you are providing. Please help us reproduce the problem with a full list of steps. Thanks

[dorp92]

Sorry about that,
there is .dvc/config containing

[core]
    remote = storage
['remote "storage"']
    url = /mnt/t/Algo/DVC

I don't remember using those flags

[dorp92]

Found the problem,
/mnt/t/Algo/DVC is a folder mounted by sshfs command.
Now I use directly the sshfs option in dvc and it works
Sorry for the waste of your time

[jorgeorpinel]

Hey @dorp92 sorry for the delay in replying and thanks for the details. No waste of time at all, this issue may help other users in the future 🙂

Found the problem, /mnt/t/Algo/DVC is a folder mounted by sshfs command

Glad you figured it out and yep, it makes sense that DVC can't push to that kinf of mount. However, I think maybe we can handle this error more gracefully/ be more informative? Cc @efiop
