如何安装本地的.deb包
usually I do dpkg -i <deb file>, it‘ll fail saying it needs dependencies.
After that when you do an apt-get update it‘ll say at the end something like "dependencies are ready to install" I think it then advises to use apt-get install -f.
Once that‘s done, I use dpkg -i again.
Worked fine for me last few years.
edit: looking a bit further, apparently a tool called gdebi can do this as gdebi [deb file]
