Trying to update computer, computer won't update for one of two errors, failed to download "check internet connection" Internet connection is fine, downloading 39 Mbps. Upgrade program says need to partially upgrade OS. Try to do this, and get failed because "ubuntu-bug ubuntu-release-upgrader-core" So now, I'm here, and can't update my computer. Tried several different verities, including attempting terminal update.
