问题

在ubuntu上使用apt-get安装软件包，系统会自动安装依赖的软件包，但是使用dpkg在ubuntu上安装软件包时不会，有时会遇到下面的错误：

pengdl@pengdl-HP:~/Soft$ sudo dpkg -i virtualbox-7.0_7.0.14-161095~Ubuntu~focal_amd64.deb

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 virtualbox-7.0 : Depends: libqt5help5 (>= 5.9.0) but it is not installed
                  Depends: libqt5opengl5 (>= 5.0.2) but it is not installed
                  Depends: libqt5x11extras5 (>= 5.6.0) but it is not installed
                  Depends: libqt5xml5 (>= 5.0.2) but it is not installed
                  Recommends: libsdl-ttf2.0-0 but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
