libev fatal error: (libev) epoll_wait / Function not implemented

Asked by Dan Cooper

Hello,
I tried to set up a ocserv VPN server.
When I try to establish the connection, I get the following message, repeatedly.
The tunnel can't be established.
Feb 14 15:04:46 pi ocserv[363026]: main[proxyuser]:[2001:470xxxx]:50878 new user session
Feb 14 15:04:49 pi ocserv[363026]: main: pinged 10.0.0.140 and is not in use

Feb 14 15:04:49 pi ocserv[363027]: sec-mod: temporarily closing session for proxyuser (session: zeZGhd)
I'm using Ubuntu 21.10 on Raspberry Pi with ARM.

The packages that seems to be affected
admini@pi:~$ apt policy libev4
libev4:
  Installed: 1:4.33-1
  Candidate: 1:4.33-1
  Version table:
 *** 1:4.33-1 500
        500 ftp://ports.ubuntu.com/ubuntu-ports impish/universe arm64 Packages
        100 /var/lib/dpkg/status
admini@pi:~$

What is the problem?
kind regards

I tried it on amd64, there it doesn't give that error.

This seems to be related to arm64 architecture, see e.g. the title in https://github.com/minio/mc/issues/2047

I suggest that you create a bug report.

Another possibility is asking upstream, probably at http://ocserv.gitlab.io/www/mail.html

Can you help with this problem?
