I just tried installing it with the command "opkg install samba" on latest Angstrom Beaglebone image (2012.05.09) and it worked. Be sure to run "opkg update" first, and check the results of that command for error messages. If "opkg update" fails, it will likely leave your package lists in a incomplete state. If it fails, just retry the command -- it has intermittent failures. Also, if you are running an old image (e.g. anything that you first installed in 2011), try using a new image. I don't understand opkg repository management, but perhaps the repositories for the image you are using have become neglected. You can install samba manually by downloading the .ipk file from its Angstrom "Feed browser" page: http://www.angstrom-distribution.org/repo/?pkgname=samba. (Note that there are different .ipk files for different Angstrom images and processors. You can figure out which one you want by looking at the path names in the output of "opkg update" on your Beaglebone. For example, if the path name is http://feeds.angstrom-distribution.org/feeds/v2012.05/ipk/eglibc/armv7a/.., then you want the "v2012.05 eglibc armv7a" version of the .ipk file.) After downloading an .ipk file, you install it with "opkg install <filename>". However, there are a bunch of prerequisite packages for samba, as listed on that Feed browser page, so if you don't already have those, you'll need to install them first. I hope that helps, Dan. Mark,

The package name of “samba” should work. I just tried installing it with the command “opkg install samba” on latest Angstrom Beaglebone image (2012.05.09) and it worked.

I have updated, upgraded and rebooted several times. I keep getting the message "Unknown package 'samba'." I am very new to linux. is there a way to manually find the correct samba package for Angstrom? Thanks Is anyone else having trouble installing samba?

Thanks for the great work!! Cris Dan,

There is also a connman script in /etc/init.d -- it appears that this script has no effect, but if connman is still running when you reboot then you should delete /etc/init.d/connman too. Dan. Hi,

Connman is running. How can I prevent connman in BeagleBone from starting up? I want to be able to enable later if I need to. I am having the same problem as “Mahmoud Tantawy “. Connman is running.
