Editing /etc/apt/sources.list breaks update
Hello Debian people! My first post here.
I have installed Debian 9.1.0 buster for i386 using the small netinst
image. Works well. I tested different desktops, too.
I wanted to use the testing branch also after buster goes stable.
According to this page:
https://wiki.debian.org/DebianTesting
it is possible by editing /etc/apt/sources.list.
I followed the instructions and changed "buster" to "testing" and
commented out security update lines.
It now looks like this :
deb http://ftp.fi.debian.org/debian/ testing main
deb-src http://ftp.fi.debian.org/debian/ testing main
# deb http://security.debian.org/debian-security testing/updates main
deb http://deb.debian.org/debian/ testing contrib main
# deb-src http://security.debian.org/debian-security testing/updates main
However running:
---
# apt-get update

Sorry, some errors are in Finnish due to my locale. I can try to
change that if required.
I found some post about GPG errors but no solutions really.
I have read some people successfully run Debian testing as a rolling
distro and the "DebianTesting" web page also says it is possible.
I am curious what is happening.
BTW, the web page has conflicting info. After an orange exclamation
mark it says:
"If you are tracking testing or the next-stable code name, you should
always have a corresponding deb http://security.debian.org <"testing"
or codename>/updates main line in your /etc/apt/sources.list ."
... although just earlier it told to remove any security lines.
This has no effect on the errors though.
Now I am testing with VirtualBox. Later my goal is to keep some old
machines alive. They only can boot from a CD, no DVD nor USB.
Distros that support installation for such machines are getting
sparse. Most distros have dropped CD size images and also 32-bit CPUs.
