Server upgrade + error

[tqb]

OpenVPN 2.4.4 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on Mar 22 2022

I run Openvpn in Ubuntu. Openvpn server for site-to-site-vpn.

1. I try add new client, and suddendly:
Can't load /root/.rnd into RNG
40032269791680:error:2406F079:random number generator:RAND_load_file:Cannot open file:../crypto/rand/randfile.c:88:Filename=/root/.rnd

I try reboot openvpn, also I try reboot computer. Not help. Next I try remove it new client ("client8"): I delete all files name contain "client8". No help.

2. How I can upgrade this Openvnp from verion 2.4.4 to any new version? Or, is it better use this old and working version?

You definitely should not be running a OpenVPN 2.4.4 at this point. Which version of Ubuntu is that? And which version of OpenSSL? If you update your version of Ubuntu you should also get a newer version of OpenVPN. Even Ubuntu 20.04 which is the oldest supported one has OpenVPN 2.4.7.

If you want the latest version we also offer packages for all supported Ubuntu versions, see https://community.openvpn.net/openvpn/w ... positories
