How can I install Steam without having to uninstall 64-bit libraries?

Solution 1:

sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450

Try running this command It was a lifesaver for many people

And this too--

sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-gl-450:i386

Solution 2:

I suggest you simply install the packages, you can have them side by side, as I have

$ dpkg -l | grep libnvidia-gl-
ii  libnvidia-gl-440:amd64                                      450.119.03-0ubuntu0.20.04.1                 amd64        Transitional package for libnvidia-gl-450
ii  libnvidia-gl-450:amd64                                      460.91.03-0ubuntu0.20.04.1                  amd64        Transitional package for libnvidia-gl-460
ii  libnvidia-gl-460:amd64                                      460.91.03-0ubuntu0.20.04.1                  amd64        NVIDIA OpenGL/GLX/EGL/GLES GLVND libraries and Vulkan ICD
ii  libnvidia-gl-460:i386                                       460.91.03-0ubuntu0.20.04.1                  i386         NVIDIA OpenGL/GLX/EGL/GLES GLVND libraries and Vulkan ICD
