Issue name

using command “dvc push -v” asyncssh.sftp.SFTPPermissionDenied: Permission denied

Description

I had some problems when using the command “dvc push”. I wanted to add some data to the dataset. I pulled from the server and used “dvc push -v”.

Then, the following error popped up.

asyncssh.sftp.SFTPPermissionDenied: Permission denied

Reproduce

git clone $url
dvc pull 
mkdir test_data
vim test_data/test_file.txt
dvc add test_data
dvc push -v

Expected

I tried ssh and sftp connection which worked well. Besides, I found that if I sampled data from the original dataset and made a copy to a new folder and pushed that folder to the server worked. I checked file permission, group and owner were all the same. Can’t figure it out .

Is there a way to fix it ? thank you !
