How to get older versions of desktop client - Linux

I'm facing an issue with my desktop client on Ubuntu 14.04 that I believe first appeared in version 2.1.0 and hasn't been resolved since. To further trace back this issue I would like to try and install a desktop client version of ownCloud with version < 2.1.0.

How can I get older versions of the client on Linux? For ease of installation and removal binaries would be highly preferred.

The changelog has download links ... https://owncloud.org/changelog/desktop/
However you might want to wait till the packages for Linux with the updated QT come out ion the next 1-2 weeks.

I've seen the links, thank you. Can you please confirm that neither sources nor binaries for Linux for, say, version 2.0.2 are available here? Sources link says "Not Found" and the Linux link just forwards to the package repository for the latest version. Something might be wrong at my end - if you can get earlier versions please tell me how you do it?

Don't worry it's not just you (https://github.com/owncloud/owncloud.org/issues/1123) We are working to bring old versions back to the changelog (as they're also important for troubleshooting as you mentioned)

Right now, the easiest way to get an older version is to build it from source: https://github.com/owncloud/client/releases. There you can get the particular version you want and compile it for your system. Might take a bit more, but you'll end with the original version you need.
