Question

linux

1. Using dpkg or apt, what would be the full command you would use to find out if the python package was installed? This is tricky because Python’s actual package name is python3.
   
   $

If it is installed, what version is installed according to the dpkg or apt output?

If it wasn’t installed, can you install it? What command would you use to do this?

$

2. Using dpkg, what would be the full command you would use to determine to which package the file /etc/rpc belongs?

$

What is the name of the package to which this file belongs?

Answer 1

Please note that all the commands are in bold

for the 1st question , you can use below command to get the corresponding packages of the python3 if it was installed.

dpkg -S python3

You can also use upto python3 installed location.

dpkg -S usr/lib/python3

The output of this command is as follows: and in my case it is python 3.5

for the 2nd question , i.e installing python in your system,

if your linux version is above 16.10 (most probably have this kind of version). then you can use the following below commands one after the other for installing python 3.6

sudo apt-get update
then below command;
sudo apt-get install python3.6

you will see below similar output for (sudo apt-get update)

for the second command you will see as below.

3rd question : Using dpkg, what would be the full command

the answer is as follows

you can use below bolded command: which will serve to search

dpkg -S /etc/rpc

the expected outcome is as below.

for the final question, the file /etc/rpc belongs to netbase package which we can clearly get it from above example

so finally dpkg has lot of uses inorder to get package search, file in the package as the above examples
