Hi,
I am installing from Proxmox VE 9.0 installer ISO , but every time it fails to unpack package 'pve-firmware_3.16-3_all.deb' and then gets aborted.
[https://enterprise.proxmox.com/iso/proxmox-ve_9.0-1.iso]

I have tried to down load the ISO couple of times and used different methods to burn it to a USB (dd on linux or rufus in Win10) but the install fails every time at the same file.
Is this a known issue with the ISO image ??

[ I have now downloaded the 8.4 ISO and installed it successfully. Will probably end up doing and upgrade.]


Thanks
SG
 
No there's no issue with the ISO image, Maybe it got corrupted during the download, did you verify the checksum?
 
Yes, I did verify the checksum.
And I did download again and used a different method to burn the USB.

The ISO boots and the install runs fine until it comes to unpack that specific deb package. And then it fails with this error.
 
Definitely not running out of space. This is a bare metal server with 64GB memory and 300GB root disk.

The error reported : (copying from a photo taken of the console) -
:
Unpacking pve-firmware (3.16.3) ...
decompressing archive'/tmp/pkg/pve-firmware_3.16-3_all.deb' (size=164178360) member 'data.tar': lzmo error: compressed data is corrupt
error: <decompress> subprocess returned error exit status 2
(subprocess): can not copy archive member from 'tmp/pkg/pve-firmware_3.16-3_all.deb' to decompressor pipe: failed to write (Broken pipe)

Then it aborts the script and finishes the install with error.
I have now used the pve 8.4 ISO and successfully completed the install, but thought I would report the failure.
 
Maybe could be a problem with your OS disk as we had somethink like similar with a redhat inst on ssd once in the past.
Do you have any other disk just to try again a pve9 inst there ?
 
Thanks for the suggestions to check other issues ...

I don't have another setup to test and I have already successfully installed pve 8.4 and configured this server, so I don't think there was anything wrong with my disk either.

So moving on ....
I may try to extract that deb packages from my pve9 iso image and check it out to verify if that is really corrupted.
