localhost:~ # update-alternatives --config g++
There are 2 choices for the alternative g++ (providing /usr/bin/g++).

  Selection    Path             Priority   Status
------------------------------------------------------------
* 0            /usr/bin/g++-11   50        auto mode
  1            /usr/bin/g++-11   50        manual mode
  2            /usr/bin/g++-7    20        manual mode

Press <enter> to keep the current choice[*], or type selection number:
