Installation Issues - Checksum

[hlago]

Is an internet connection necessary to install VME? In my test labs, I have never encountered an error when installing it, but I am trying it in another environment without internet access and I am receiving the following error:

I' m using the following ISO: HVM_Install_24.04.ISO_S5Q83-11033.iso I have checked the md5 and it is all correct

Hello @hlago 
Hope you are doing well.

No — an internet connection is not strictly required to install VME from the official ISO.
The error message confirms the installer fails its media check before/during install. It's almost always a problem with the ISO image or how it was written to the media, not with having no Internet.
Here are few steps to resolve it.
>Re-verify the ISO
>Recreate the install media
Use a raw-write method (dd on Linux/macOS or Rufus in DD mode / balenaEtcher). Avoid simple file copy or tools that alter the image.
Try a different USB stick and a different USB port (use a rear-panel port on desktops).
If you used a virtual mounting tool, instead write the ISO to disk rather than mounting.
>Check for corruption during download
If the checksum doesn’t match, re-download the ISO (preferably over a different network) and re-validate checksums.
>If everything else fails
Re-download the ISO and recreate media first (this fixes 95% of checksum errors).
If a newly downloaded ISO still fails checksums, please contact HPE support for further assistance.

The installation is being performed on an HPE ProLiant Compute DL325 Gen12 server. I mount the ISO (located on my computer) from the iLO and start the installation. I can't use this method; do I have to do it from a USB drive? Installing from the iLO makes the task much easier.
