### Description Much of this issue is repeated from [#2018](https://github.com/kamailio/kamailio/issues/2018). Since it's closed and has no activity, I'm opening this issue. Kamailio 5.3.3 won't start when using `kamailio-tls-modules` on Ubuntu/18.04.4 unless `tls_force_run` is set in kamailio.cfg ``` $ grep CRITICAL /var/log/kamailio/kamailio Apr 14 17:18:39 kam-01 /usr/sbin/kamailio[22073]: CRITICAL: tls [tls_init.c:677]: init_tls_h(): installed openssl library version is too different from the library the kamailio tls module was compiled with: installed "OpenSSL 1.1.1 11 Sep 2018" (0x1010100f), compiled "OpenSSL 1.1.0g 2 Nov 2017" (0x1010007f).#012 Please make sure a compatible version is used (tls_force_run in kamailio.cfg will override this check) Apr 14 17:18:39 kam-01 /usr/sbin/kamailio[22073]: CRITICAL: <core> [main.c:2768]: main(): could not initialize tls, exiting... ``` ``` $ cat /etc/apt/sources.list.d/kamailio.list deb http://deb.kamailio.org/kamailio53 bionic main deb-src http://deb.kamailio.org/kamailio53 bionic main $ $ dpkg -l | awk '/kam/ { print $2 " " $3 }' kamailio 5.3.3+bionic kamailio-extra-modules:amd64 5.3.3+bionic kamailio-mysql-modules:amd64 5.3.3+bionic kamailio-snmpstats-modules:amd64 5.3.3+bionic kamailio-tls-modules:amd64 5.3.3+bionic kamailio-websocket-modules:amd64 5.3.3+bionic $ $ /usr/sbin/kamailio -v version: kamailio 5.3.3 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 7.3.0 $ $ /usr/bin/openssl version OpenSSL 1.1.1 11 Sep 2018 ``` -- You are receiving this because you are subscribed to this thread.
