Hi, The actual stable munin (2.0.33) in the portage tree is not compatible with python3. The python3 compatibility has been added upstream since then (on 3 Jun 2017): https://github.com/cgzones/munin/commit/1fda8fb3e58e7fa6333eb8c4fd888e75fa182ed9#diff-929dfde415f1f32f53ac94b09682af2a and the 2.0.34 has been released on 21 Oct 2017. But, 2.0.34 is marked as ~arch, so the gentoo’s stable munin is still not compatible with python3, and python3 is default interpreter. So, I’m wondering if it possible to stabilise 2.0.34. Thanks, -- Alarig Le Lay
munin 2.0.34 is now stable and munin 2.0.33 has been removed.
