Error on startup: `GLIBC_2.29' not found

[Davem734]

Using: Ubuntu 18.04.6 LTS

Installed: tribler_7.12.1-RC2_all.deb

Error on startup: $ /usr/share/tribler/tribler [24775] Error loading Python lib '/usr/share/tribler/libpython3.8.so.1.0': dlopen: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /usr/share/tribler/libpython3.8.so.1.0)

My understanding is that the highest version avalable on Ubuntu 18.04.6 is `GLIBC_2.27'

@Davem734 Ubuntu 18.04 is no longer supported in the release. However, you can try building from the source here: https://tribler.readthedocs.io/en/latest/building/building.html

Thank you for your help. I tried and there seems to be an issue at this step:

$ pip3 install --upgrade -r tribler/requirements.txt
