I'm trying or atleast was trying to update the adblock package to the 2.6 version from the snapshot repo. I added the repos i thought were required into the custom section except it did not connect for me. I think it was a wget 4 error.
I am on the latest 17.0.1 rlease branch and the most up to date package is 2.4..x.x.
Would someone be willing to give me a pointer or something?
Likely you have not installed SSL certificates (ca-certificates package) although you try to use HTTPS links for downloading. Normally packages are downloaded from the repo with HTTP. If you really want to use HTTPS, please install all needed packages.
Secondly, it is usually not a good idea to try using master packages in an older release branch firmware. Likely they will not work. "adblock" should work as it is pure scripts, but generally is is a bad idea to add release repos to your opkg. (Release builds use different kernel versions, possibly also a different musl version, so very likely the packages will not work and may even brick your router.)
Thirdly, it would be much easier to just download the single adblock package .ipk file with wget to the router, and manually install it with opkg. (or download it to your PC, transfer with scp to router, and then use opkg to install the .ipk)
Finally, I have just backported adblock 2.6.2 to the 17.01 and the buildbot is currently crunching it. You can install it (and the updated LuCI app) soon from the normal 17.01 repo after buildbot has got the updated package built.
