I'm currently looking at a patch to fix this. In the meantime, you could add the following packages to your build manually via local.conf to see if it solves the issue for you: python-pyhamcrest python-debugger python-unixadmin 86136 2 sherpya 2020-01-29 14:39:22 +0000 unfortunately there is no python3-pyhamcrest so I had to patch twisted package 86137 3 tvgamblin 2020-01-29 14:43:11 +0000 Right. I actually have submitted patches for the zeus branch, but in the meantime you may have to make manual additions if you are using python3. 86138 4 sherpya 2020-01-29 14:44:16 +0000 nevermind, it's not a big deal, I've made a small patch for twisted and it works, I'll removed it when it will be merged 86139 5 tvgamblin 2020-01-29 14:45:53 +0000 Sounds good. I'll close this then if you have a workaround for now. 86166 6 tvgamblin 2020-01-29 21:29:19 +0000 Reporter has a workaround, and patches have been submitted to fix the dependencies for master and zeus.
