”optional feature not implemented” with crypt-on-sftp in 1.66
What is the problem you are having with rclone?
I’m using a crypt-on-sftp remote, which was working just fine up until v1.65.2. With v1.66, attempts to sync to it now fail with ”optional feature not implemented”. I’ve not narrowed down whether it’s the crypt or the sftp layer, so I’m just reporting my (failing) test case below.
I did a bisect, and apparently this issue came in at f5f8678 (which was a fix for #6685).
What is your rclone version (output from rclone version)
1.66.0
Which OS you are using and how many bits (e.g. Windows 7, 64 bit)
Ubuntu 22.04 (64-bit)
Which cloud storage system are you using? (e.g. Google Drive)
sftp
The command you were trying to run (e.g. rclone copy /tmp remote:tmp)
rclone sync a/ C:
Steps to reproduce
rclone --config test.conf config- set up sftp (44) remote called S
- for test purposes here I’m using localhost as the underlying remote server
- set user & password
- leave everything else at defaults
- set up crypt remote C, with
- ”S:ftp” as the underlying remote
- Very simple filename obfuscation (obfuscate)
- Encrypt directory names (true)
- set password, no password2
mkdir -p ftp a/b # on the sftp remote; here I'm using localhosttouch a/test1 # on the sftp remoterclone --config test.conf sync a/ C: -vv # no problemstouch a/b/test2 # on the sftp remoterclone --config test.conf sync a/ C: -vv
A log from the command with the -vv flag (e.g. output from rclone -vv copy /tmp remote:tmp)
