Hi, I suspect this probably happens because the patch doesn't automatically link against libpthread.so for glibc versions prior to 2.34, and results in link failure, and I think Ubuntu Focal uses glibc-2.31 as system libc ? For glibc >= 2.34, libpthread.so was integrated into libc.so, so should work for that.
