Hello,

since yesterday afternoon, there are "update failed" error-messages in my /var/log/pveam.log file. Before, the daily-morning update was successful.

I have already executed apt-get update && apt-get upgrade.
Everytime, when I execute "pveam update" from pve shell, the same errors will occur.

Here is the content of the library directory
root@pve:> ls -l /var/lib/pve-manager/apl-info
total 72
-rw-r--r-- 1 root root 11664 Apr 5 05:30 download.proxmox.com
-rw-r--r-- 1 root root 58118 Apr 5 05:30 releases.turnkeylinux.org

First, I thought this could be a problem with access-rights ..., but when I download / gunzip manually, it works…

cd /var/lib/pve-manager/apl-info
wget https://releases.turnkeylinux.org/pve/aplinfo.dat.gz
gunzip aplinfo.dat.gz
ls -l
total 132
-rw-r--r-- 1 root root 58118 Nov 20 08:22 aplinfo.dat
-rw-r--r-- 1 root root 11664 Apr 5 05:30 download.proxmox.com
-rw-r--r-- 1 root root 58118 Apr 5 05:30 releases.turnkeylinux.org

So, currently the problem is, that I cannot setup new LXC-Containers based on Proxmox Helper Scripts, because they make an update of the templates and breaks before creating the container with "update failed - see /var/log/pveam.log for details".

Has someone an idea ?

Thanks,
Markus

Don't use apt-get upgrade on Proxmox; always use apt-get dist-upgrade: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#system_software_updates

It works fine here (but I have never run community helper scripts). What is your Proxmox version (pveversion -v)? Maybe your drive is almost full (df -h /)?

Those scripts are not provided by Proxmox. Maybe the people that do develop and maintain them can help you here: https://github.com/community-scripts/ProxmoxVE/discussions ?

But the problem is a general problem with pveam update

I have done additional tests: pveupdate is working (which is called from the daily-executed service-unit)
Code: 
pveupdate
cat /var/log/pveam.log

2025-04-05 12:05:16 update successful

So, why there is a problem only with pveam update but not with pveupdate ?
What is the difference between pveam update and pveupdate ?

I have looked into the source-code, but seen nothing special with the gunzip:
pve-manager / VE / APLInfo.PM,
sub download_aplinfo {
...
eval { run_command(["gunzip", "-f", $tmpgz]) };
die "update failed: unable to unpack '$tmpgz'\n" if $@;
...

Hi,
please share the full output of pveversion -v. Do you have any proxy/firewall/similar configured (e.g. http_proxy in /etc/pve/datacenter.cfg)?

You could try to modify the line for the error message and then re-run pveam update on the CLI to hopefully get a more descriptive error:
die "update failed: unable to unpack '$tmpgz' - $@\n" if $@;
