Hi,
I have been using this thread: https://askubuntu.com/questions/1143268/how-to-install-a-libc6-version-2-29#_=_
to be able to install GLIB 29 which worked. Now there is an issue coming up regarding libcurl.so4... Ubuntu 18.04 comes with libcurl.so3 which is needed by many programs and software. Also, to make things worse, libcurl.so3 and libcurl.so4 cannot exist next to each other. Though version 4 can be downloaded for Ubuntu 18.04.
I will keep working on it and let you know if I find a solution.
Cheers
