</span>Unchanged activities will *not* work on current Debian. Not stable, not<br>
testing, and not unstable. Nor will they work with Ubuntu.<br>
<br>
You might get them to work by adding "telepathy-gabble-legacy", but<br>
beware that that package is *old* and *unsupported* and *insecure*!<br>
<br>
Likewise, support for conventional tubes-based collaboration on other<br>
systems - OLPC OS and Fedora - makes use of an outdated version of<br>
telepathy Gabble, which potentially is highly insecure to use.<br>
