How can I install "gdb-arm-none-eabi" on Ubuntu 18.04 (Bionic Beaver)?

I had the same question, and googled some more. It seems that with modern GDB you no longer need a GDB for your specific architecture. Just use GDB.

(seems to work on my older 16.04 workstation as well. I've been typing arm-none-eabi-gdb all those years, while just "gdb" would've worked just as well! .....)

As far as I can see, there are two options:

• Install an old version (as pointed out by Chaos)
• Install gdb-multiarch, which actually worked for me.
