grep: symbol lookup error: grep: undefined symbol: pcre_jit_stack_alloc

Hi, I tried to package Ubuntu 12.04 game into AppImage and run it on 20.04.

app: c501checkers
union: true

ingredients:
  package: c501checkers
  dist:    precise
  sources:
    - deb http://old-releases.ubuntu.com/ubuntu/ precise main universe
  ppas:
    - colingille/freshlight

script:
  - cp ./usr/share/c501checkers/data/icon.png ./c501checkers-icon.png

This is what I get after running the AppImage:

user@hp-laptop:~/Downloads/pkg2appimage$ ./out/C501_Checkers-1.1.3+precise1.glibc2.14-x86_64.AppImage 
grep: symbol lookup error: grep: undefined symbol: pcre_jit_stack_alloc

Any ideas how to fix that?
