Developer Tavis Ormandy, who works on Project Zero for Google, has ported the Unix versions of Lotus 1-2-3 and WordPerfect to Linux as a finger exercise. The Lotus port had already become known in May 2022. Then in July 2022, Ormandy was able to announce the port of WordPerfect to Linux – The Register wrote this article about it. He wrapped it all up in a .DEB package to allow easy installation on Ubuntu and Debian distributions. WordPerfect was quite popular in the 80s and early 90s – I used it mostly on Dec VAXes running VMS. However, with the raise of Word for Windows, this word processor has overtaken WordPerfect.
