SOLVED: Cannot Access Web UI and App

Let's purge and start over. Since /var/lib/jellyfin doesn't exist, that means you have no data to lose, correct?

Code:

sudo apt purge jellyfin*
sudo rm -rf /etc/jellyfin /var/lib/jellyfin /var/cache/jellyfin /usr/share/jellyfin
curl https://repo.jellyfin.org/install-debuntu.sh | sudo bash
