Various install scripts fail due to OpenWRT's release candidate package naming scheme

[VITALISED]

A variety of scripts such as the Adblock install script use the pattern [0-9][0-9-]+ to find package versions. This does not seem to work with the current set of OpenWRT packages which all seem to be release candidates (i.e adblock_4.2.3-r2_all.ipk)

I found that [0-9][0-9-]+(-r[0-9])') generally helped as a workaround in these cases, however I don't really have the time to PR anything.

Hope this helps and that I'm not just blazingly incompetent somehow

Thanks for the report. I have made some changes that I hope will fix it.
