That's a much longer list and I don't know if this is useful. There are packages in there that don't mean much to me. Did the same as before; saved both to a file and did a diff. This is the result of the diff.
Most likely it will remove some package you have installed, but because it will ask for confirmation you can note what is going to remove, and eventually reinstall later.
Alternatively you could install qt4-network on the machine where octopkg is working, as see if installing that lib is going to broke octopkg.
Done. Rebooted > no change; Octopkg still has the same error.
It seems 'qt4-network' came with SMPlayer. I Blame NevilleGoddard for that, he recommended that player on this forum...
But seeing where that came from, I know for sure that Octopkg did not work BEFORE I installed SMPlayer
I'm unable to spot anything relevant ... other than that qt4-network lib. I'm also out of ideas right now.
Hopefully someone else might see something, reading the thread that we are missing. Thanks for your time/tests/trials.
