I needed gcc 5 on my ubuntu 22.04. I tried using "sudo apt-get install gcc-5 g++-5" but this output is coming:
sudo apt-get install gcc-5 g++5

E: Unable to locate package gcc-5
Now what does last line indicate ...any solution. I have already added the repository using "sudo add-apt-repository ppa:ubuntu-toolchain-r/test" and have done sudo update.
It still is showing same result.
