I maintain an out-of-support Ubuntu 12.10 (Quantal Quetzal) server (don't ask me why, please), and we need to patch the Shellshock Bash security bug. As upgrades are not available anymore, what is the recommended way to patch Bash?
I found this answer (it recommends retrieving packages from Debian and to not install binaries packages, but install packages from source). That seems OK to me, but what is some other advice?
