Questions[minitube](ubuntu)

For building the minitube ( https://github.com/flaviotordini/minitube ) I need to have a version later than the one offered by the repositories. The reason I am asking is because the developer supports Later Ubuntu versions than the LTS one (18.04)

So I need to build it by myself. Also, I have installed previous versions of minitube by manually compiling it.

Based upon this answer I used the ppa:beineri/opt-qt-5.12.0-bionic but misses the qttools512-dev-tools package hence the build fails on:

/opt/qt512/bin/lrelease locale/ar.ts -qm build/target/locale/ar.qm
make: /opt/qt512/bin/lrelease: Command not found
Makefile:904: recipe for target 'build/target/locale/ar.qm' failed
make: *** [build/target/locale/ar.qm] Error 127

SO how I can install a later version of qt in order to build the minitube. Also keep in mind that the solution should not require the whole QTCreator because I find it kinda bloated in norder to use it just for a built.

When I run minitube from terminal I get:

No available API keys 
403 "Error downloading https://www.googleapis.com/youtube/v3/search?part=snippet&type=video&maxResults=50&q=teste - server replied: Forbidden" 202

Is there a way to fix this?

I really enjoy using Minitube. It's a very comfortable and lightweight alternative to YouTube playback with flash. The only thing that bothers me is that I have to manually copy and paste interesting youtube links I found into the program to play them back.

Is there any way I can automate this and integrate Minitube into Google Chrome or another web browser?

I'm using Minitube 2.1, and I was under the impression that it has it had an automatic playlist. Do you have to enable that feature or what?
