Can't install PVE 8.1 either in GUI or Terminal, it gets stuck directly at boot

[XabiX]

Hi All,

Unfortunately mu upgrade from 8.0 to 8.1 was a disaster (not sure why maybe bc I nvidia testal packaged installed and he was not able to compile correct for 6.5).
I tried to boot in Ubuntu to recover files but root was ok to be mounted (but can't get /etc/pve), I couldn't seem to get data LVM mounter so I have to resintall and I am scared it will be taking a while to recover. As I don't have qemu on ubuntu, I am not sure if I can export the LVM/VGS 'disks' into files or ext drives to re-install quickly.

By way is the installer not working (UEFI with or without Secure boot it s the same):


Merci

Please see the documentation.

Yes, nvidia drivers can cause such problems. If you have problems with upgrades, please post everything you've done and every output there was on the screen.

It's not part of a default install, yet it is installable.

Yes, you can, but having proper backups before upgrading your system is the way to go.

Hello,

I gave up and I installed Debian and then Proxmox as just booting the Proxmox USB Installation gives me the above screen and doesn't work. I tried GUi, CLI, console menu items and they all fail in launching the Proxmox fresh installation.

I was able to install from a PVE 8.1 live USB stick by doing this :

1. Boot from USB choosing the UEFI entry in the boot menu
2. Move the cursor of the TUI installer option
3. Press "e" to edit, replace "vga=xxx" at the end of the line with "nomodeset"
4. Press Ctrl-X to boot with your changes

I solved! ty
