Hi,

since yesterday we have a hash sum mismatch in the no-subscription repo that we use for testing before we update the prod servers with enterprise subscription.

Example:

Code: 
Fehler: Fehlschlag beim Holen von http://download.proxmox.com/debian/ceph-squid/dists/trixie/no-subscription/binary-amd64/ceph-mgr_19.2.6-pve4_amd64.deb Hash-Summe stimmt nicht überein

Anything wrong with the Release file and the Hashs?
 
Hi @G0ldmember

thanks for reporting this!

Tested on my end but here the checksums match.

What CDN host does your PVE node use to download and does the issue persist?
Code: 
host download.proxmox.com

Best regards
Jonas

Hi, it's

Code: 
download.proxmox.com is an alias for download.cdn.proxmox.com.
download.cdn.proxmox.com is an alias for de.eu.cdn.proxmox.com.
de.eu.cdn.proxmox.com is an alias for de.cdn.proxmox.com.
de.cdn.proxmox.com has address 212.224.123.70
de.cdn.proxmox.com has IPv6 address 2a01:7e0:0:424::249
 
Just checked the package from that mirror and on my end it also matches the Packages file.

Could you please try again on your machine?
 
In the Packages file there's
Code: 
Filename: dists/trixie/no-subscription/binary-amd64/ceph-mgr_19.2.6-pve4_amd64.deb
Size: 1233888
MD5sum: 5d870e8aebfdaac08865f5be41dfb0fd
SHA256: e9926085a2db087f920b49116e5b6a57766c12383f433ea2e8cfdb864d3c937a
SHA512: 52cfe658cecc59cd81a021af964975720154e4fa839d5533ffe9393b5f3815e528ce7f02f78dc998bf7bf2fc93ed08bb9899fef491dcab3a7679b0fdce90efaf

But the actual files checksum is

- SHA512:81e97d8493054533b2a047925e441225e6de3ba4e7ff0edc03c018e01ce827b021b47842b32ba829140923368f8b191af311c886219d6a34fbbe81f5c3308985

Now it's a different CDN node :)

That's unexpected, especially since it is the same wrong checksum both times.

I think we have established that the CDN is fine so let's focus on your system.
What kind of storage are you using for the root disk and what kind of NICs?
In the best case please provide the following:
Code: 
uname -r
lscpu
ethtool <uplink-NIC>
ethtool -i <uplink-NIC>

Best regards
