2. Use the dpkg command to install

dpkg is a low-level software package management tool in the Debian operating system. Unlike apt, dpkg cannot automatically resolve a package's dependencies, so you need to manually install its dependent packages before installing the .deb installation package.

sudo dpkg -i [deb包名]

Where [deb package name] is the name of the .deb installation package you want to install.

sudo apt-get install -f
