same issue here.
I upgraded to proxmox 5 but no web gui...

Also, previously (with proxmox 4) when the system was started I could see the login prompt and the proxmox url.
Now with de upgrade, only login prompt is displayed, there is no proxmox url info.
 
Fixed. I followed some instructions from there:

I edited /etc/apt/sources.list and replaced by https://pve.proxmox.com/wiki/Package_Repositories but proxmox was never installed. After I added this line to sources:

deb http://download.proxmox.com/debian/pve stretch pve-no-subscription

after apt-get && apt-get dist-upgrade

It installed a lot of packages but not proxmox. I tried with apt-get install proxmox-ve but no way, I have to use this line to do so:
wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

After that it installed proxmox-ve and I´m ready to go.

Thanks!
