Issue in ubuntu versions 16.04 and above.

[Antonyrahul]

Looks like the package uses libpng12-0 as a dependency in ubuntu machines. But libpng12-0 is not available in versions greater than 16.04 . Since new pprojects are deployed in 18.04LTS and 20.04 LTS the compression does not work as they have a libping version more than 12. The module throws the error "error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory" . Please fix this

I may have the same problem as you. I'm running well on my Debian 9 and I've got a bug on Debian 10
