I can't login to my Proxmox Web Interface!

[naupe]

Recently I set up my Proxmox for port 443. Unfortunately, since I've done so, I'm unable to login to the Proxmox GUI!

I've tried logging in as root and a Guest Admin Account I created. Both give me back the following message:

Login failed. Please try again

I can login to both account when SSHing to the Proxmox Server in Putty, it's just the Web Interface that is giving me this issue. I've never had Login issues until now.

This issue has come up in a couple threads around here and this seemed to be a workable solution:

https://forum.proxmox.com/threads/r...cluster-reinstall-on-debian.49128/post-229665

Tried this myself, but I still can't login through the Proxmox Web Interface.

Alright, so NOW the Proxmox Web Interface comes up! Here is what I've done, and I don't know if it's a longterm solution:

wget http://download.proxmox.com/debian/pve/dists/stretch/pve-no-subscription/binary-amd64/libpve-access-control_5.1-12_amd64.deb
dpkg -i libpve-access-control_5.1-12_amd64.deb

Since I downloaded an older version of libpve-access-control, and now I went back to the previous (and more updated) version.

apt --fix-broken install
apt-get install pve-manager

pve-manager has unmet dependencies apparently:

The following packages have unmet dependencies:
libpve-guest-common-perl : Breaks: qemu-server (< 6.1-19) but 5.0-56 is to be installed
libpve-storage-perl : Breaks: qemu-server (< 6.1-14) but 5.0-56 is to be installed
pve-cluster : Breaks: qemu-server (<= 6.0-13) but 5.0-56 is to be installed
pve-ha-manager : Depends: qemu-server (>= 6.0-15) but 5.0-56 is to be installed
pve-manager : Depends: qemu-server (>= 6.2-17) but 5.0-56 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

But THIS was what I installed to allow me to login to the PVE Web Manager again:

apt-get install libspice-server1

At the end however, I was given the following warning:

W: (pve-apt-hook) !! WARNING !!
W: (pve-apt-hook) You are attempting to remove the meta-package 'proxmox-ve'!
W: (pve-apt-hook)

E: Sub-process /usr/share/proxmox-ve/pve-apt-hook returned an error code (1)
E: Failure running script /usr/share/proxmox-ve/pve-apt-hook

I have NO idea why! I am quite worried there is a lot of misconfigurations with my Proxmox VE 5.4-2 (which I know is old, but I'm not quite sure what I need to do to upgrade from 5.4-2 to 6.X).

Hi,
what is the output of pveversion -v and how does your /etc/apt/sources.list and files in /etc/apt/sources.list.d look like?

So you already configured the repositories for PVE 6. You should switch back to stretch instead of buster for now and fix up the installation. Please run apt update and apt dist-upgrade afterwards. Do not continue with the upgrade if it still wants to remove proxmox-ve. PVE ships its own pve-libspice-server1 which conflicts with libspice-server1, so you cannot install the latter.

Only after apt is happy again, try upgrading to PVE 6, following this guide.
