How to install the latest filezilla to Ubuntu 14.04 LTS laptop

[botg]

The usual compiler is GCC, and available from https://gcc.gnu.org/

Installing-c17-and-c20-on-ubuntu
would the following work:

[42] #1
"run the following commands to add
the Ubuntu Toolchain repository:"

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update

[42] #2
"Once updated the apt, install them with the following
commands:"

$ sudo apt install gcc-10 gcc-10-base gcc-10-doc g++-10
$ sudo apt install libstdc++-10-dev libstdc++-10-doc

[42)#3 how ?
&
is flag needed to build filezilla client ?

"Then you need to tell the compiler to use
the C++20 standard by using the
-std=c++20 flag"

[42)#4
"Check that libs got installed :"

$ apt list --installed gcc-10*
$ apt list --installed g++-10
$ apt list --installed libstdc++-10*

https://gasparri.org/2020/07/30/install ... zon-linux/

or just ?

[42)#1
$ sudo apt install g++-17
$ g++ --version

and ?

[42)#2
create hello.cc

#include <iostream>
using namespace std;

int main()
{
cout << "Hello, World!" << endl;
cout << "This code is compiled with G++ version: " << __GNUC__ << "." << __GNUC_MINOR__ << "." << __GNUC_PATCHLEVEL__ << endl;
return 0;
}

$ nano hello.cc
$ g++ -o hello hello.cc
$ ./hello

No idea as to the above. I'd start reading here: https://gcc.gnu.org/install/

You do need a newer compiler. As stated before:

The folloging finally failed, why ?

1. Ctrl+alt+T (ok)

2. updated all the repositories

$ sudo apt update

3. installing g++ failed, why ?
3.1
~ it looked like my Ubuntu laptop
was not able to fetch all required
compiler component although
net connections are ok, why ?

3.2
~ some IP addresses my Ubuntu laptop
tried were not available/did not respond
why ?

3.3
