Thanks for your post and bringing all those broken download links to my attention. Most of those are broken because the appliances haven't been updated for a while (for various reasons) and one of my colleagues did an unannounced purge of all the old images. Unfortunately he didn't consider the broken links it would leave...

Regardless, some of them probably should have been removed anyway and even the ones that are still ok to use should have included a note that they were old versions and why.

However, Ibexa and Sahan Eden were both caused by me - mistakes I'd made meant the download links were wrong. I've now fixed them. FWIW Ibexa has been recently updated, but Sahana Eden hasn't been updated for a while. The upstream development has stalled, so we may need to drop that one too.

I've gone through the other ones that you note and are no longer available and added notes of why and removed the download links. The reasons are varied, but include no longer being developed upstream, outdated dependencies and other technical issues. So I have removed the download links and added a note to the top of each of their pages giving context to why they are no longer available.

I think that I've done them all, but I should double check again. I'm going to leave that for now as I've already spent a long time tidying those up and I'm trying to catch up on everything after having a couple of weeks off.

If you notice any other issues please do not hesitate to let me know. Bug/issue reports are always warmly welcomed.
