One thing about doing an OS reinstall..

.. is that it reminds you what programs you're actually using when you can't find them any more.

For updating here, I use Drivel as a Linux client. It's not been updated in years, to the point that Debian dropped it as a package at some point since the release of Wheezy in 2013.

I'm a bit surprised that no-one seems to have done anything better, on Linux at least. Is there one I'm not aware of?
