kurento media server gstreamer 1.5/1.0, glib

[st...@belochka.kz]

good day,

help plz, so I do not have enough knowledge to solve it

problem started after upgrading bbb from ~2.2.11 to 2.2.3x through 

apt upgrade

apt downloaded new version of kurento-media-server 

~$ kurento-media-server -v

Kurento Media Server version: 6.15.0

As far as I understand new version works with gstreamer1.5, but previous builds in 2.2.11 work with gstreamer1.0 (i think so). 

~$ systemctl status kurento-media-server

if change it to /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0.4800.2 and a few more similar files (libgobject and etc) from *6400* to *4800* kurento starts to work correctly (comes to life). This solution i got in article about glib https://medium.com/@Aenon/glib-symbol-lookup-bug-in-debian-or-ubuntu-def678dab5a6

after that the problem is that everything works for a while, but after 5-7 days the symbolic links automatically (without my intervention) fall into the old places and the kurento falls off again with error which I described above. Tell me in which direction I need to look to fix this bug?

the reason why files of alternative glib files appeared on the server - 

earlier I tried to install a new version of the glib for setting up the latest version of janus-gateway.

No. Kurento always used gstreamer1.5 (which is their fork of gstreamer 1.8).

Can't you purge the derelict glib version, bust the ldconfig cache/linking, clean the gstreamer registry and then see if that works?
