Yes,
Out of interest it says the following at Perplexity,
=========================
Will ubuntu for RISC V have a compatible app repo?
Answer
Yes, Ubuntu for RISC-V will have a compatible app repository. Canonical has been actively porting Ubuntu packages to RISC-V architecture, and as of 2025, 97–98% of Ubuntu's packages are already ported to RISC-V. This ensures robust compatibility and software availability for RISC-V platforms.
Additionally, Canonical plans to leverage the RVA23 Profile, which guarantees software portability across compliant RISC-V chips. This means that a single binary can run on all RVA23-compliant devices, further enhancing app compatibility for Ubuntu on RISC-V
=========================
so all Ubuntu's APPS work on Risc V
