Hm,
A “clean” Mint install shouldn’t pull from deb.volian.org on its own. 
That repo only shows up if:
- You installed something like nala (apt frontend). The nala .deb package adds the Volian repo automatically.
- Or you restored/imported a package list that included it.
Mint’s stock repos are all under linuxmint.com and ubuntu.com. If you don’t recall installing nala (or similar), you should look into that.
As such, if you don’t actually need it, just remove the repo file under /etc/apt/sources.list.d/ and you’re back to a pure Mint base.
Should be using deb http://deb.debian.org/debian

I have seen similar errors when attempting to use a local mirror from Update Manager, when questioned with the following:
Do you want to switch to a local mirror?
From what I have seen, the local mirrors are rarely kept in synch.
In Update Manager’s Software Sources, switching back to the default mirror should correct the issue.
“Update Manager” → menu “Edit” → “Software Sources” → tab “Official Repositories” →
Mirrors: Main (vera) http://packages.linuxmint.com
Mirrors: Base (jammy) http://archive.ubuntu.com/ubuntu
I think the button “Restore the default settings” sets it to what is shown above. If not, you can do it manually.
The aforementioned repositories are the default for Linux Mint v21.1 / Vera (derived from Ubuntu v22.04 LTS / Jammy Jellyfish).
Once you get it working, and if you have multiple systems running the same version of Linux Mint, please consider apt-cacher-ng.

hi i,ve tried but still have same error W:Updating from such a repository can’t be done securely, and is therefore disabled by default.,
You’ve added an untrusted third-party repo that isn’t recognized or verified by your operating system.
To fix this, you should remove the problematic repository from your system’s sources, verify its authenticity, or just disable it it.
APT is blocking that repo for safety because it can’t verify its signature. You’ve also got an extra issue: at least one file in /etc/apt/sources.list.d/ has a bad filename extension, which APT ignores.
USE THE FOLLOWING AT YOUR OWN RISK AND ONLY IF YOU KNOW HOW TO REVERT:
In the meantime, try this to fetch Volian’s repo key and store as a keyring:
sudo mkdir -p /usr/share/keyrings
curl -fSsL https://deb.volian.org/volian/scar.key \
| gpg --dearmor | sudo tee /usr/share/keyrings/volian.gpg >/dev/null
Also use HTTPS and the keyring
echo 'deb [signed-by=/usr/share/keyrings/volian.gpg] https://deb.volian.org/volian scar main' \
| sudo tee /etc/apt/sources.list.d/volian.list
Then update
sudo apt update
Or…
Please paste the results of these command:
ls -la /etc/apt/sources.list.d/
