FreeBSD 12.3 python38-3.8.15 The error is not specific til 5.5.2 since I am upgrading from NAV 5.2.1. ipdevpoll will not start: Traceback (most recent call last): File "/usr/local/bin/ipdevpolld", line 19, in <module> from nav.ipdevpoll.epollreactor2 import install File "/usr/local/lib/python3.8/site-packages/nav/ipdevpoll/epollreactor2.py", line 24, in <module> from twisted.internet import epollreactor File "/usr/local/lib/python3.8/site-packages/twisted/internet/epollreactor.py ", line 16, in <module> from select import epoll, EPOLLHUP, EPOLLERR, EPOLLIN, EPOLLOUT ImportError: cannot import name 'epoll' from 'select' (/usr/local/lib/python3.8/lib-dynload/select.cpython-38.so) Am I missing a library or a module? This is a bit urgent since I really don't want to downgrade... --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo@uit.no Dep. of Information Technology --- Univ. of Tromsø
