APT not working due to certificate singing

[waahmed12]

Hello everyone,

I have recently installed proxmox and installed some VMs.
When I try to update proxmox or any Linux VM, APT refuses to download or install any packages due to certificate signing

I tried many solutions such as adding enterprise key and removing
adding [trusted=yes] to the repositories and all security bypasses in https://manpages.debian.org/stretch/apt/apt-secure.8.en.html

Is your PVE maybe behind a proxy?

Is your PVE maybe behind a proxy?

Yes it's,

but all the links and IPs related to the repos are whitelisted and allowed
I can for example access ubuntu repo links and IPs and they are not blocked

Did you setup /etc/apt/apt.conf to use the proxy (like "Acquire::https::proxy "https://proxyserver:8080";")? Also if you use a HTTPS proxy you need to change...

deb http://ftp.debian.org/debian bullseye main contrib
deb http://ftp.debian.org/debian bullseye-updates main contrib

...to...

deb https://ftp.debian.org/debian bullseye main contrib
deb https://ftp.debian.org/debian bullseye-updates main contrib

... and so on.
