@givemeaname sounds like a faulty cable to me then. On my Nexus 5 it also sometimes has issues with losing connection, but normally the installer resumes as well if the cable isn't super bad.

@givemeaname https://github.com/ubports/ubports-installer/releases/tag/0.8.6-beta use the snap if you can and try Ubuntu maybe, not familier with Fedora myself.. Also don't forget wipe and bootstrap when asked.
