Hello,
I'm trying to compile the YUN's image following the instructions on this page Arduino Playground - Yun
The build process continue until it stops on trying to download crmtp server package 's files from SVN : it said it is unable to authenticate with the server and it fails... (and it seems an anonymous login)
anyone with the same problem?
Thanks you
P.S: it's a great product, full of potential! 
a nice upgrade from UNO!
Hi dega1999
Unfortunately, not every package definition is stored on github. A greater number of packages are available in what openwrt (linino is a fork of it) calls "feeds". These feeds are not under our control and sometimes they may fail.
In order to build the image I try to enable as many packages as I can, so that you can install them on the yun, disabling those that fail as soon as I get an error
I suggest you to do the same. You can also update the feeds re-executing
./scripts/feeds uninstall -a
rm -rf feeds
./scripts/feeds update -a
./scripts/feeds install -a
and re-try.
Thanks you Federico, I will try and keep updated about it
