Ubuntu 20.04 seems to have removed certain includes which have already been marked as deprecated for a longer time. This commit upates those include paths and it also contains a missing include statement (errno.h) in one of the files
I believe the attr/attribute.h is part of libattr1-dev package, which doesn't seem to be necessary anymore. Could you please also remove it from the README?
