1. Simpler installation method
Open the terminal directly with crtl+shift and run the following command.
sudo add-apt-repository multiverse
sudo apt update
sudo apt install steam
The first is to add support for third-party non-free software libraries, which means that the system supports third-party non-free software; the second command is to update the software package, and the third is to install steam. In fact, the central solution of this article is to open support for third-party software.
At present, only a startup program is installed, and the main program has not been downloaded and updated. Enter steam to download and install at the command line:
2. Complicated solutions (not recommended)
Some friends, like me at the time, downloaded the deb package directly from the steam official website. Since the package on the official website is 32-bit, our majority of 64-bit friends are sad, and we need to let the system download the library that supports 32-bit. Happy installing steam.
