Question 1

Я работаю

sudo apt-get install libboost-all-dev

и все же я ничего не вижу в моем /usr/include каталог для повышения.

Все же папка повышения все еще отсутствует.

Почему происходит?

Question 2

Ваши библиотеки Boost отсутствовали, потому что Вы Вы, непреднамеренно не установили его. Команда, которой я предоставил Вам в комментариях, была проверкой установки. Если бы библиотеки были правильно установлены, то вывод был бы просто несколькими строками.

первая строка Вашего вывода была:

0 upgraded, 27 newly installed, 0 to remove and 2 not upgraded.

Это показало, что 27 пакетов отсутствовали и установленные при обработке команды.

команда Install/Reinstall:

$ sudo apt install --reinstall libboost-all-dev

Вывод:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 1 reinstalled, 0 to remove and 0 not upgraded.
Need to get 0 B/2,228 B of archives.
After this operation, 0 B of additional disk space will be used.

Unpacking libboost-all-dev (1.58.0.1ubuntu1) over (1.58.0.1ubuntu1) ...
Setting up libboost-all-dev (1.58.0.1ubuntu1) ...

Теперь, когда Повышение правильно установлено, переустанавливание только покажет 10 строк, если переустановлено. Эта командная строка покажет Вам, Ваше повышение включает каталог:

$ ls -ld /usr/include/b*

вывод будет приблизительно двумя строками:

drwxr-xr-x 103 root root 12288 Jan 16 17:01 /usr/include/boost
-rw-r--r--   1 root root  1404 Nov 16 17:43 /usr/include/byteswap.h
