我在Ubuntu上安裝了「apt-get install」的python3.4。從源代碼手動安裝python 3.4.1是否正確覆蓋了python 3.3的apt-get安裝？從python 3.4.1源手動安裝是否能正確覆蓋Ubuntu的現有python 3.4安裝？
例如，Ubuntu安裝在/usr/lib/python3.4中有文件，而在https://www.python.org/ftp/python/3.4.1/Python-3.4.1.tar.xz中的安裝程序在其他幾個位置存放文件。
如何正確刪除apt-get install？或者，源代碼是否會正確地覆蓋舊的目錄？
用apt-get remove (package)刪除。與hello例如：
# sudo apt-get remove hello
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
hello
0 upgraded, 0 newly installed, 1 to remove and 245 not upgraded.
After this operation, 111 kB disk space will be freed.
Do you want to continue [Y/n]?

獲取來源，有了正確的路徑 - 它被Debian化（Ubuntu的也可以）
$ apt-get source hello
走進源，並建立一個二進制軟件包它
$ cd hello*
$ fakeroot debian/rules binary
然後安裝新鮮的二進制包：
$ sudo dpkg -i ../hello*deb
Selecting previously unselected package hello.

或者，從這裏安裝Ubuntu（Debian）Python 3.4.1二進制包：https://packages.debian.org/search?keywords=python3
