Thanks for reporting this. Can you tell me how you were accessing the sftp server? Which program were you using and what did you do with it? This is crashing because rclone is receiving an sftp command it doesn't handle "Readlink". I've changed the code so it returns an unsupported error for this rather than crashing. This will probably work now, but may produce errors in the calling application so more work may be needed - let me know what happens!

As you might remember from the thread about mount in Windows, I'm trying to get rclone to be mounted as a network drive in Windows systems. In the meantime, as a workaround, I tried to use SSHFS-Win ([https://github.com/billziss-gh/sshfs-win](https://github.com/billziss-gh/sshfs-win)) to mount it. As long as credentials are entered, rclone crash. ---

Thanks for the info. Can you try the beta above and see if it fixes it? ---

rclone doesn't crash, but SSHFS-Win can't report the free/total space of the remote, when it does it perfectly for my Raspberry Pi. ---

Unfortunately the library rclone uses doesn't support the extended sftp call necessary to show free/total space: [https://github.com/pkg/sftp/issues/236](https://github.com/pkg/sftp/issues/236) Does it work otherwise? I've merged the above fix to master now which means it will be in [the latest beta](https://beta.rclone.org) in 15-30 mins and released in v1.50 ---

I found a bug in the above fix so I suggest you try [the latest beta](https://beta.rclone.org) in about 20 minutes from now! ---
