          @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?

            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.py script 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?
