Question Concerning Bullseye Security Updates

I still have a problem concerning a line in my update/upgrade sources.list.

The line is:

deb bullseye/updates main

The offending error from that line is:

// start

Err bullseye/updates Release
404 Not Found [IP: 80]

// end

Does anyone have a solution?

I use aptitude, on the command line

You have a spaces in the url.

curl -I " bullseye/updates main"

And that has a tree.

You'll need to post more info for more answers.

OK... the full 'sudo aptitude update' is:

kevin@Shatner:~$ sudo aptitude update

Ign bullseye/updates InRelease
Hit stable InRelease
Err bullseye/updates Release
404 Not Found [IP: 80]
Hit stable InRelease
Hit bullseye InRelease
Ign InRelease
Ign stable InRelease
Hit stable Release
Hit Release
E: The repository ' bullseye/updates Release' does not have a Release file.

To upgrade to testing from current stable, if you have already installed the stable release:

Edit your /etc/apt/sources.list file, changing 'stable' (or the current codename for stable) to 'testing' (or the current code name for the next stable release).

Remove or comment out your stable security updates line(s) (anything with in it).
Remove or comment out any other stable-specific lines, like *-backports or *-updates.
There isn't actually anything in security for Bullseye. The nature of "testing" everything is under development... if there were a security issue it would be fix rather than a security patch! exist for compatibility moving forward. If you look, all the contents files never change.
