The problem is that EPGimport change the compression algorithm it was using, we switch from gz to xz to have better compression rate.
So you need to install packages that support xz format on your old image and also update EPGimport to its very latest version.
in the download link they already xz
Of course but your version doesn't support them, so no unzip so 0 event loaded!
but now i'm on openpli 6.2 the openpli4 not workong image so all the componemts is update izma and html and compresion plugin
as i already mention openpli now availlable for unsupported box but you get to build your own image
