I started using TurnKey Hub about a month ago. I manually upgraded the TKL appliance to MediaWiki 1.22 shortly after deploying and life was good. Yesterday the MediaWiki install stopped working, in spite of the fact that there had been no activity for the last few days. I suspect the failure was caused by a security update that was pushed out to my virtual appliance. Unfortunately, the update is to a much lower version of MediaWiki than I was using.

By turning off Semantic MediaWiki extensions, I could see that the version is now 1.19.16+dfsg-0+deb7u1, which is not compatible with my requirements. When I searched on the version string above, I found that yesterday there was a Debian Security Advisory (see http://www.securityfocus.com/archive/1/532412), and 1.19.16+dfsg-0+deb7u1 is the fix...

I am pretty sure I can get the wiki running again by manually reinstalling a newer version again. I will upgrade to 1.23 while I am at it.

My question is: How do I prevent this from happening in the future? Seems that Debian is not in sync with the latest MediaWiki updates.

Thanks,

Rodger
