Install an older version of Gimp on a newer OS

I've been trying to downgrade to Gimp 2.8.22 on Linux Mint 20, which is based on Ubuntu 20. I have been unable to find pre-made binaries for Linux (though [plenty exist for Windows and Mac](https://download.gimp.org/gimp/v2.8/)) . The narrative goes "Simply compile the source!" but I am unable to do this because a few dependencies (such as gegl 0.2) are apparently not available for modern Ubuntu-based systems. Does anyone know of a way to get Gimp 2.8.22 on newer Linux systems? Hopefully something statically linked? Or at least have a guide on building this given modern constraints? I have tortured myself with Gimp 2.10 for the last two years thinking one day I'll enjoy it. But the more I use this software the more I fear I'll finally break and inject myself with hydrogen cyanide while laughing hysterically.
