pi-safe install issue in ubuntu server 20.04 LTS 2

[arsirantala]

Hi,

I did not have lua installed in the ubuntu server initially. I installed it with following command:

sudo apt-get install liblua5.1-0-dev liblua50-dev liblualib50-dev

Then I attempted again to install pi-safe and got following errors:

Install needed tools:  PiShrink, zip,  and xz-tools?

Any ideas what lua version I need to install ubuntu server? I presume ubuntu server is supported?

Lua version is:
Lua 5.0.3 Copyright (C) 1994-2006 Tecgraf, PUC-Rio

Found a way to get the pisafe to work - had to install newer version of lua:

sudo apt install lua5.3

Case closed :)

New version 0.9.18 should address that.
Thanks for letting me know.
