problems installing salome 9.12.0 on ubuntu 22.04?

I recently downloaded the latest version of salome. It has been very frustrating to be adrift. I can’t find any relevant information on how to fix the problem. Would you be so kind as to instruct me on the installation and correct operation of salome?
When I run it in the terminal I get this message:
bash: ./salome: no such file or directory

you need to proceed as follows:

# 1- Extract SALOME
tar zxf SALOME-9.12.0-native-UB22.04-SRC.tar.gz
cd SALOME-9.12.0-native-UB22.04-SRC

# 2- ensure that you installed python-is-python3, if not, run:
#      sudo apt install python-is-python3
# 3- then, ensure that you have missing system dependencies installed:

sat/sat config SALOME-9.12.0-native --check_system

# 4- install with apt all reported missing dependencies
# 5- launch SALOME with 

./salome  # or ./mesa_salome (embeds a MESA layer)

Finally, note that if you’re running wayland, you need to fall back to X11. Have a look at other threads mentioning this issue.
