[Qgis-user] Working with second band of two-band GeoTIFF
I only recently switched to QGIS 3, so I am not sure whether I am missing something that was moved to a different place or the handling of raster layers changed. I am using 3.6.0 on a Mac. I have a two-band GeoTIFF image, and I want to run the Raster Calculator on the second band of the image. When I open the Raster Calculator, it only shows me band 1 of the image (image_name@1). I tried forcing it to use band 2 with @2, but that did not work. I looked at layer Export->Save As and I don’t see a way to save the second band there.

I'll ask one of the devs with a mac to have a > look. If all fails I remove plugins.qgis.org from Cloudflare caching. Ok, confirmed here now. I have removed the Cloudflare caching for now...

[Qgis-user] Plugins repository unavailable for 2.18?
Hello, Has something changed about the plugins repository for version 2.18? I have not yet upgraded to version 3.x, and sometime in the last month or so the plugins repository (https://plugins.qgis.org/plugins/plugins.xml/?qgis=2.18) has stopped working for me.
