Trouble with libolm on debian stable

[kp9001]

I'm trying to install on debian stable. For libolm, I followed the instructions here and everything appears to have gone well. By which I mean, I got through the make and test steps without errors.

In any case, when I run pip install -r requirements.txt I am met with this error. Any idea what I can do to resolve it? Anything else I can check for to make sure the libolm build went well and things are in the right place?

You probably need to sudo make install in the olm build directory.

@kp9001 Are you sure you have libolm3? I needed to install https://packages.debian.org/buster-backports/libolm-dev and https://packages.debian.org/buster-backports/libolm3 from backports.
