Hey,
In the last few days i can't update my opkg, seem it's beacuse the link is not download the correct file when updating opkg.
If you have problem with opkg that you cant install new package and when you try the command:
opkg list
It show you the installed problem, i have a fix for you:
Change the link in /etc/opkg.conf from:
src/gz snapshots http://cloud.wifipineapple.com/packages
To:
src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages
This is the same directory anyway but this fix the bug.
I belive that the administrators fix this asap but until then, you're not stuck.
if you got problem with this talk to me,
