[SOLVED] No web interface after pve 9 upgrade!

What was I thinking
You are missing the Debian repositories. That would hinder Promxox packages as they depend on Debian. You also have the no-subscription and the enterprise repository both enabled. Your also have other repositories enabled which may or may not interfere with Proxmox. This could have been discovered six hours ago.
Maybe disable those netdata repositories temporarily and chose between no-subscription and the enterprise repository for Proxmox.Definitely add the Debian repositories: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_debian_base_repositories before trying to install packages and update your system.

EDIT: When and why did you decide to remove the Debian repositories (which are mentioned in the upgrade guide your linked)?
I disabled those sources because I thought they were automatically going to be included in the new proxmox.sources. Obviously not haha, I just did the update, thank you.


The enterprise ones are commented out. I wonder why they refuse to share the ouput of apt update though. I asked about it too.
Thanks, I missed that. @alex01763, it would have been more clear and more idiomatic if Enabled: false would have been used instead.
I disabled those because I never used those repositories so I didn't need them. I didn't know about the Enabled flag, I'll look into them, thanks for letting me know!

Now it is stuck in UEFI and won't boot but I'll open another post for that and mark this as closed. Thanks for all the help!
