- Reinstall from that USB, use defaults
- Check the system with the commands from the thread
- Bit by bit add the apps you need, but do not add repos ( aside from maybe the videolan repo, but follow the wiki instructions I provided elsewhere )
This should give you a reliable, stable system and when support is needed something that those who try to help can relate to.
And, last but by far not least: Do not do first when in doubt, but ask.
