@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.
