It is the meta-yocto-bsp/lib/oeqa/controllers/beaglebonetarget.py complaining about missing python module "pexpect". I could speculate the module was previously included with python2.7 by default but it is not installed by python3, at least for some Linux distros. However, I suspect this problem has always been there. Manual installation : $ sudo pip3 install pexpect should fix the problem. So the most prudent fix is to update the documentation explicitly stating pexpect is required http://www.yoctoproject.org/docs/1.8/ref-manual/ref-manual.html#required-packages-for-the-host-development-system 69778 2 juro.bystricky 2017-01-12 23:18:35 +0000 Punting this to Scott, as the need for "pexpect" should be documented. 69951 3 srifenbark 2017-01-20 00:00:59 +0000 Juro, So installing the "pexpect" package for all supported distros. I assume that it needs to be in the "Essentials" grouping (see http://www.yoctoproject.org/docs/2.3/ref-manual/ref-manual.html#required-packages-for-the-host-development-system) Thanks, Scott 70047 4 juro.bystricky 2017-01-23 20:33:51 +0000 yes, I believe that is exactly what is needed. 70060 5 srifenbark 2017-01-23 22:37:56 +0000 Juro, See http://www.yoctoproject.org/docs/2.3/ref-manual/ref-manual.html#required-packages-for-the-host-development-system for the changes in the ref-manual. See http://www.yoctoproject.org/docs/2.3/yocto-project-qs/yocto-project-qs.html#packages for the similar section in the YP Quick Start. If this is ok - let me know. Thanks, Scott 70069 6 juro.bystricky 2017-01-23 23:36:09 +0000 Looks good to me. (And it should be probably back ported to previous Yocto documentation as well, this is not a new requirement) 70071 7 srifenbark 2017-01-24 00:35:05 +0000 Backported to top of yocto-docs/morty branch. See ref-manual at http://www.yoctoproject.org/docs/2.2.1/ref-manual/ref-manual.html#required-packages-for-the-host-development-system Backported to top of yocto-docs/morty branch. see YP Quick Start at http://www.yoctoproject.org/docs/2.2.1/yocto-project-qs/yocto-project-qs.html#packages Scott 70089 8 juro.bystricky 2017-01-24 17:40:52 +0000 Looks fine. Both pip3 and pexpect are always needed: pip3 in order to run toaster and build Build Appliance pexpect is (and has always been) needed by beaglbone testimage 70100 9 srifenbark 2017-01-24 21:51:44 +0000 Thanks Juro, I am setting the bug to RESOLVED and putting the doc flag to "done."
