Yeah, I noticed the same thing. Odd… I’m guessing it’s part of a list that isn’t configured by default on the BeagleBone’s install. If I figure it out, I’ll let you know, but in the meantime you can manually install the package from your link and use opkg to install it.
Okay, yeah, the reason is because for some reason the sudo package is only listed under the armv7a base feed and not the armv7a-vfp-neon base feed which is what BBB uses since those applications are compiled with the extra extensions. If I was more familiar with Ångström, there’s probably some incantation to tell it to supplement the base feed with an alternate feed.

This is likely just an miss from the Ångström folks.
