Testing sources.list

[elwyud]

I would like to upgrade from stable to testing. Which repositories do I add to my sources.list?

Is the following correct?

Code: Select all

deb http://ftp.uk.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ testing main contrib non-free

deb http://security.debian.org/ testing-security main contrib non-free
deb-src http://security.debian.org/ testing-security main contrib non-free

Moving from Stable to Testing isn't an upgrade. In fact, in many respects, it's a downgrade. Packages are in Testing because they're not always stable, so there are significantly increased chances of something crashing your system. More importantly, security updates take longer to get through to Testing, meaning that you could be exposed.

If there is a particular package that has a feature that you specifically need, but the version in Stable doesn't have that, then backport that package only. At least the rest of your system will be stable.

I would like to upgrade from stable to testing.

Why? You do understand that Testing is not an upgrade? That it breaks? That it's not for beginners?

If you have to ask you're probably not ready.

If you have to ask you're probably not ready.

I ask because the Debian Administrator's Handbook seems to be out-of-date. It gives an example sources.list in §6.1.3. with the following for testing security:

Code: Select all

deb http://security.debian.org/ testing/updates main contrib non-free

However, I believe it has now been changed to:

Code: Select all

deb http://security.debian.org/(debian-security/) testing-security main contrib non-free

I note that there's a testing-updates repository (http://ftp.uk.debian.org/debian/dists/testing-updates/), but it isn't mentioned in the handbook.

I note that there's a testing-updates repository

Please check Security support for the testing branch, chapter 10.1.4

I think both still work. I would use https://deb.debian.org instead though, that covers Security. But having said that testing is the worst choice if security is a concern (see the above posted link for more on this).
