The fix is rather straightforward and easy, but I'll include the explanation for a better understanding.
So the error is thrown by the awk tool which first appeared on the scene 42 years ago in 1977. It is certainly amazing that tools of that age are still used for non-legacy things, but why exactly does it prevent us from installing PetaLinux to our machine?
Searching for the answer leads us into the Debian alternatives system:
dzu@zarniwoop:~/Downloads$ awk --version awk: not an option: --version dzu@zarniwoop:~/Downloads$ ls -l /usr/bin/awk lrwxrwxrwx 1 root root 21 May 28 17:17 /usr/bin/awk -> /etc/alternatives/awk dzu@zarniwoop:~/Downloads$ ls -l /etc/alternatives/awk lrwxrwxrwx 1 root root 13 May 28 17:17 /etc/alternatives/awk -> /usr/bin/mawk dzu@zarniwoop:~/Downloads$
So the default awk flavor of Ubuntu 18.04 is not the continuously improved GNU awk but rather a minimal POSIX compatible implementation called mawk. Xilinx indeed documents the requirement of gawk in UG1144 on page 10, but the same document forgets to mention it in the "Quick Installation of Packages" section for Ubuntu.
So all in all, fixing the problem is straightforward:
dzu@zarniwoop:~/Downloads$ sudo apt install gawk Reading package lists... Done Building dependency tree Reading state information... Done Suggested packages: gawk-doc The following NEW packages will be installed: gawk 0 upgraded, 1 newly installed, 0 to remove and 58 not upgraded. Need to get 401 kB of archives.

This automatically takes care of installing gawk as the preferred awk flavor and is enough for the PetaLinux installer to run correctly:
