+ cd amd64/gcc-12-ubuntu
+ docker build -t gcc-12.1.0:ubuntu-20.04 .
+ docker run --rm --entrypoint cat gcc-12.1.0:ubuntu-20.04 /gcc-12.1.0-1-ubuntu-20.04.deb > /tmp/gcc-12.1.0-1-ubuntu-20.04.deb

+Now you can install it:
+
+ sudo apt install -y /tmp/gcc-12.1.0-1-ubuntu-20.04.deb
+
+Set gcc-12 as high priority:
+
+ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 12
+ sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 12
+
+For convenience, add `/usr/lib64` to `LD_LIBRARY_PATH` environment:
+
+ export LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH
+ echo "export LD_LIBRARY_PATH=\"/usr/lib64:\$LD_LIBRARY_PATH\"" >> ~/.bashrc
