rsync: change_dir failed

[xade93]

Hi all,

as the title describes, reMy refuse to connect. Terminal output:

I am able to ssh into remarkable normally with ssh root@192.168.12.234.

Hi, sorry for the late response. Looks like the path /home/root//'/usr/share/remarkable/templates is wrong in that it contains a spurious ' but I'm not sure where that comes from... If you set "log_verbosity": "debug" in your configuration you'd be able to see the full rsync command issued, and that could give us some clue.

For more details you could add

    log.debug("RSYNC command: %s", ' '.join(cmd))

after line 475 in remy/remarkable/filesource.py

Hi, I have been encountering the same error for a couple of days. Changing the source type to ssh works fine, but if I try rsync I get the following output using your suggestions:

I hope that sheds some light on the issue.

just a quick additional remark: if I remove the quotes from remy/remarkable/filesource.py:462, i.e., make it
return "%s@%s:%s" % (self.username, self.host, path)

then everything works fine. (But I understand that things may break if there are spaces in the paths)

[bordaigorl]

@arieder thanks for the feedback! Indeed this seems to be an issue with quoting. The path is taken to be '/usr... which has the side-effect of making it a relative path, so it gets expanded to /home/root/'/usr... which is all sorts of wrong. Can you change line 462 with: return '%s@%s:"%s"' % (self.username, self.host, path) (note the switch of quotes). Does it work then?

[arieder]

Unfortunately it does not. (It no longer fails to connect completely, but that might be because now there is a valid templates folder from before). I get the following output:

[I] DATA STORED IN:
        /home/alex/remarkable/documents

[bordaigorl]

Ok. I guess that argument does not need quoting. It seems like a platform-specific issue though. What OS/Python/RSync versions are you using?

[arieder]

I am using:

Manjaro Linux with Python 3.10.4 rsync version v3.2.4 protocol version 31 (on my PC) rsync version 3.1.3 protocol version 31 (on my remarkable)

[bordaigorl]

Ok, I pushed a fix on devel I'll see if this is causing other platforms to fail.

[arieder]

thank you for the quick response. For me, it works now.
