In README i saw that 20.04.6 is compatible with lazyjournal, but in reality it seems not...its not super old distro...its my postgres production server and i cant upgrade it to 22.04 due to compatibility reasons with other software

ldd --version ldd -> ldd (Ubuntu GLIBC 2.31-0ubuntu9.17) 2.31
apt-get install -y libc6 -> Newest libc6 already installed (2.31-0ubuntu9.17).
