[Qgis-developer] suggestion for "PPA for qgis" instructions page

[Christian Gunning]

I'm following the instructions for QGIS PPA here:
https://launchpad.net/~qgis/+archive/ppa

I'm excited to see that PPA is now using signing keys.  This means
adding the key to the keyring.  The instructions page above include a
link to the PPA web page  -
(https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories)
- with instructions that point to a screencast... too many links for
me! Besides, it's *really* simple...

The R install page has the following instructions for adding their key
to the keyring.  By changing the key ID, they work perfectly.  Maybe
this could be added to the instructions page?  If people want to know
more, they can follow the link to the detailed instructions, but i
think most people don't need this much info...

hope this helps,
christian

SECURE APT

The Ubuntu archives on CRAN are signed with the key of "Vincent Goulet
<vincent.goulet at act.ulaval.ca>" with key ID E2A11821. You can fetch
this key with

   gpg --keyserver subkeys.pgp.net --recv-key E2A11821

and then feed it to apt-key with

   gpg -a --export E2A11821 | sudo apt-key add -

Some people have reported difficulties using this approach. The issue
was usually related to a firewall blocking port 11371. An alternative
approach is to search for the key at
http://keyserver.ubuntu.com:11371/ and copy the key to a plain text
file, say key.txt. Then, feed the key to apt-key with

   sudo apt-key add key.txt
