I tried to install it on ubuntu 16.04 LTS, and Software Center informed that the 4KDownloader 4.12 package can not be installed due to violation of qualtity standard.
This was the message: Lintian check results for /home/angkd/Downloads/Softwares/4kvideodownloader_4.12.0-1_amd64.deb: E: 4kvideodownloader: malformed-deb-archive newer compressed control.tar.xz.
what should I do?
