You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libc++1 : Depends: libc++1-10 (>= 10~) but it is not going to be installed
libopencv-highgui2.4v5 : Depends: libpng12-0 (>= 1.2.13-4) but it is not going to be installed
open3d-viewer : Depends: libglfw3 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

在没有第三方存储库的全新 Ubuntu 20.04 LTS 系统上，您必须使用 apt 安装此包来解决依赖关系：
wget -c https://github.com/intel-isl/Open3D/releases/download/v0.12.0/open3d-app-0.12.0-Ubuntu_20.04.deb
sudo apt-get install ./open3d-app-0.12.0-Ubuntu_20.04.deb
上述软件包不需要libpng12。
在您当前的情况下，您必须提供有关所用依赖项的其他信息。
