@Chico008 said in XOA - Vm linux install keep failing since updateing XCP to 8.3:
tried using uefi (non secure) or bios, each time install failes.
ISOs comme from my NAS, and VM disk are hosted on a ISCSI Lun
on 8.2 was exactly the same conf, sources, all worked fine, but now i can't :/, and i'm unable to understand the report, i only it failed during kernel install.
my Isos are the same i used for 8.2, on the same NFS Share.
tried installing a win 2K19 server, seems ok, but Ubuntu server can't (even tried a ubuntu server 22, same)

Could you post the ISO version you were using for the installation and hardware details?

@dinhngtu
iso : ubuntu-24.04.3-live-server-amd64.iso
Sha256 is correct comparing to Ubuntu web site.But, it may not be because of Xcp :
Tries installaling a new VM on our Vsphere, with the same Iso from different source, same error
seems to be an issue when kernel is downloading from web during install
-
Ok this is it
seems some Ubuntu mirror are having issue, install offline by disconnecting lan card, install finished fine.

@acebmxer Maybe, did you try an offline install, this solved my issue, then after install i could update/upgrade normally.

@acebmxer Did the
fix-efivars.pyscript fix the Ubuntu installation issues for you? If so, which version of varstored do you have, did you install varstored 1.2.0-3.3 following our blog post? -
@dinhngtu
Yes if you follow the link to the post i created i go into a little detail but yes i followed everything in the blog. It fixed my Ubuntu 24.04.3 install issues. -
Thanks for the information.
@Chico008, does the information at https://xcp-ng.org/blog/2025/10/30/xcp-ng-8-3-varstored-update-unbootable-vm-risk-and-remediation/ resolve the issue for you?

@dinhngtu Hi
For my i made on offline Install to solve my issue, installed failed when downloading the kernel from servers, so offline install worked fine for me.
