Riddle me this, team.

How, out of all the vendors providing software out there, does this one distro consistently have so many bad downloads?

And then, just to make it spooky on top of weird, some of those downloads actually run installs and can go as far as building undead systems that are missing parts.

Sure.
EVERY software provider is plagued by bad downloads.
And there's some chance of ANY download having some oddball effect.
But this happens ALL THE TIME.

Wassat all about?
 
I am not aware of a particular high number of "bad ISO downloads" - I just think you might see more reports because there's a very active community here in one place..

if you in particular frequently see corrupted ISO downloads on your end, please provide details (can also be done privately).
 
Thanks Fabian. Yes, it's an anecdotal impression. But a strong one.
And yes, the fact that there even is a (very well maintained) forum to come and complain certainly does aggregate and highlight the complaints.
And yes, there are a LOT of bad downloads. Is it worse than anywhere else? Can't say.
But I've had a couple bad downloads, (three bad installs so far pbs and pve) and I cannot figure out why.

I appreciate the offer of help. If I had a clue, I'd have posted that instead. Currently zero clues.

Heh. Might as well resurrect your headache from last year.
They made all these same points. Same non-conclusion.
The internet is a funny thing. Except it isn't. its a whole stack of funny things. And sometimes they work funny.

Thread 'proxmox-ve_8.1-2.iso Corrupt ISO file from official mirror'

Dear Proxmox staff,

I'm a new user and when trying to install proxmox virtual environment from Ventoy I encountered issues similar to other peoples' experience with installation media not finding the ISO file when launching the installer (disable quite kernel command line parameter in grub). So I thought it's a Ventoy issue and flashed the ISO with dd on another usb flash drive which was not bootable at all. I also couldn't mount the usb on my system so I actually checked the ISO and noticed it has a different sha256 checksum than it should have.
  1. Afterwards got it working doing the...

Hey ... um ... where can I get checksum values for old ISOs? Is there an ftp archive or something?

the next time you experience a bad download, please check
- the file size (i.e., is your download truncated?)
- try running a tool like vbindiff on it and a good copy to check which parts are different, usually you will see some pattern there (e.g., a single bit/byte flipped somewhere? 4k worth of data mixed up? whole chunks being swapped? ...)
- describe *how* you downloaded it (browser? curl/wget/..? torrent? ...) and ideally if you know, from which server and at which timestamp (a simple "ping download.proxmox.com" and posting the IP should suffice). if you want to provide your client outgoing IP to us (privately?) that would probably help with correlating logs as well
 
I've just been using the same tools as always. Download via Chrome on a Windows server hosted on PVE w ZFS.
The mounts were iDRAC HTML5 console sessions. Chrome again.

I learned how to use the PS Get-FileHash.
It's annoying that I have to do so, but there's clearly a problem that I need to guard against until I figure it out or it stops being a problem.
I've not yet found a bad download.

Thanks again for the offer of help. When and if I hit on something unexplainable, I will definitely reach out.

that might explain it - in my (admittedly limited) experience, those often don't work well for bigger iso files.. the samba/CIFS based access often works better, an actual physical USB stick with the iso works best ;)
