Why are programs not installed via apt-get install?

Question

ubuntu

Good evening, I ran into a problem that programs cannot be installed on Ubuntu 14.10 through the package manager.
Here is the log:

I'm trying to run:
sudo apt-get update --fix-missing
Here's what it says:

Restarting does not help, this error happens with any program. What to do?

Answer 1

The Utopic Unicorn version (14.10) has 9 months of support, which means the repositories have not been available for a long time. Install either 15.10 or 14.04 LTS. With this version, you will no longer install or update anything, the old distribution.

Answer 2

The repositories of this junk have already been removed from the mirrors.

sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

Answer 3

You should read in this direction: http://help.ubuntu.ru/wiki/guide_on_ubuntu_s... But most likely the apt-get module became crooked during installation. If I understand correctly, the system is freshly installed? If so, it's easier to just reinstall the system.

Answer 4

Update the repository.
Here is a good generator

Then apt-get update, apt-get upgrade .
