I want to install some applications but for any installation command it says that this package has no installation candidate. I can't even run sudo apt-get update. 

cookie98@cookie98**:~$ sudo apt-get install software-properties-common
[sudo] password for cookie98:

Package software-properties-common is not available, but is 
  referred to by another package.
This may mean that the package is missing, has been obsoleted, or is
 only available from another source

E: Package 'software-properties-common' has no installation candidate

    If you cannot run sudo apt-get update your system is seriously ill or there is no connection to the internet. Which version of Ubuntu are you running (for example 16.04 LTS? How did you install it? Did you upgrade it? What is the output of the following command: uname -a – sudodus Jan 22 '18 at 15:56

    "not working" is a bit vague. Please edit your question to include the complete output of sudo apt-get update and sudo apt-get upgrade – user535733 Jan 22 '18 at 16:44
  • What do you mean by 'I upgrade'. Did you upgrade the release from 17.04 to 17.10? Or do you mean that sudo apt-get upgrade did not work? 2. I agree with@user535733, please give us the complete output of sudo apt-get update and sudo apt-get upgrade -- edit the original question and indent each line of the output 4 spaces to render it as 'code'.

    Please give us all the error output of apt-get update as edit of your question – Robert Riedl Jan 22 '18 at 18:22
  • Did you changed /etc/apt/sources.list and /etc/apt/sources.list.d ? Did you tried to switch to other mirror with software-properties-gtk? – N0rbert Jan 22 '18 at 20:25
