debian testing repos

[MMonty1960]

I am sorry, I just installed LMDE. I love the rolling edition concept and I hope to solve the following question to adopt definitively LMDE. For my work I need of some packages, like opencv and libserial. But the manager refuse the full opencv installation and libserial is not listed. On the other hand these packages are in debian squeeze repo. What is the best way to install packages from debian squeeze or testing? Should I add the debian repo or is there a method to directly install a particular package? Thank you for any answer.

The only way i know is adding the debian repos temporarely, refresh synaptic, install the wanted packages, disable or
delete the Debian repos and refresh synaptic again.

OK. Could you give me detailed information on how add the testing repo? In particular where can I find the GPG key? Sorry but I am not much skilled on that.

You open yor sources.list with

Code: Select all

gksu gedit /etc/apt/sources.list

then copy and paste the line

Code: Select all

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

to disable it add a # in front of the line.

You can do the same with stable or unstable repos

Code: Select all

deb http://ftp.debian.org/debian stable main contrib non-free

Code: Select all

deb http://ftp.debian.org/debian unstable main contrib non-free

Don't forget to disable the repos after you've installed the wanted packages and refresh synaptic.

The debian-keyring should already be installed. If not you find it in synaptic.
