Octa8on :
Try debugging and copy the result here - I mean the file "/tmp/feed.log".
wget -qO- --no-check-certificate "http://updates.mynonpublic.com/oea/feed" | bash -xv > /tmp/feed.log 2>&1
You can also check the contents of the "/etc/opkg" directory, where the softcams feed source (a file named "*-secret-feed.conf") should appear after a successful installation.
