ubuntu help program is not useful. If I click to ubuntu-software, by prepared applications appears VLC_media player. After demand installation of this, ubuntu-software was blocked. All other applications work without problems. Answers of Mr. Hampl /german) were not useul, bedcause the installatin of ubuntu 16.04 with CD works. What can I do to install new software at 16.04.
Otherwoise ubuntu 18.04 doesn't work, because I use windows 10. Grub can not be installed
