s3ql post-installation script fails with syntax error in "yield from"

[Neal McBurnett]

After the last s3ql package upgrade, on precise, I started getting this error:

Setting up s3ql (1.18-1~precise1) ...
SyntaxError: ('invalid syntax', ('/usr/lib/s3ql/dugong/__init__.py', 409, 18, ' yield from self._co_send(("CONNECT %s:%d HTTP/1.0\\r\\n\\r\\n"\n'))

dpkg: error processing s3ql (--configure):
 subprocess installed post-installation script returned error exit status 101
Errors were encountered while processing:
 s3ql

It seems that the post-installation script noted is relying on the new "yield from" feature that was only introduced in python 3.3 (PEP 380).

Where did you get this package version from?

The most-recent s3ql package in the official precise repository is 1.9-1 (see http://packages.ubuntu.com/precise/s3ql). The most recent s3ql package for precise in the ppa is 1.18.1-1~precise1 (not 1.18-1~precise1, see https://launchpad.net/~nikratio/+archive/ubuntu/s3ql/+packages).

Either of these packages should work fine.

Thanks for noting the newer package in universe. And I'm sorry for my typo in the package version.

This is where I was seeing what is actually 1.18.1-1~precise1, in the ppa:

$ wajig policy s3ql
s3ql:
  Installed: 1.18-1~precise1
  Candidate: 1.18.1-1~precise1
  Version table:
     1.18.1-1~precise1 0
        500 http://ppa.launchpad.net/nikratio/s3ql/ubuntu/ precise/main amd64 Packages
 *** 1.18-1~precise1 0
        100 /var/lib/dpkg/status
     1.9-1 0
        500 http://us.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages

I just removed that nikratio ppa and removed the package, than installed s3ql again and that install worked fine.

I haven't looked back at the version in the ppa, but it does seem like if it used python3-only stuff, it would fail on precise.
