Hy, can you tell how you solved it? It may help future users also using Ubuntu 😁
I removed the Pixelorama program installed via snap because the new version requires the GLIBC_2.28 library, which I don’t have. The error looked like this: /snap/pixelorama/199/Pixelorama.x86_64: /lib/x86_64-linux-gnu/libc.so.6: version ‘GLIBC_2.28’ not found (required by /snap/pixelorama/199/Pixelorama.x86_64) After removing the snap version, I went to itch.io, downloaded Pixelorama from your page, extracted the archive, and ran it through the terminal using the command ./Pixelorama.x86. Everything works, and I am using the program now.
