Can't install Skype

[0chk]

Hello.
I'm a total newbie who wants to see if I can work with Ubuntu. My issue is installing Skype. I have Ubuntu 16.04 LTS and 64-bit system. I have enabled Canonical Partners. When I try to install from the Terminal I get a very long error message. Here is a selection of screenshots.

Thank you

It is easier for others to help you if you post the actual terminal input/output between code tags rather than posting images of the terminal.

What's the output of

cat /etc/apt/sources.list

I'm sorry, but I'm totaly new to Linux and didn't udnerstand your feedback.
Terminal dispalyed more than a 100 Error messages and then a long list of "Failed to fetch".
I tried again and got:
E: Could not open lock file /vab/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

Thank you

This is enclosed in code tags

E:  Could not open lock file /vab/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

It means that when you ran that command you did not put sudo in front of the command and therefore you where not requested to enter your user password. Certain tasks require us to be the administrator or "root" as it is called in Linux.

At the start of the block of text put the word code inside square brackets [ ]. At the end of the block of text put /code inside square brackets. We can do the same the word quote for a similar effect.

Thank you.
I tryed again with puting sudo in front of the command. it doesn't tell me about root anymore But doesn't work yet;_;
The last line is

 E: Unable to fetch some archives, maybe run apt -get update or try with --fix-missing?

.
I did run sudo apt-get update and it didn't help, sudo --fix-missing is an unrecognized option

sudo --fix-missing is an unrecognized option

Its is

 sudo apt-get update --fix-missing

I suggest you run it using just apt and in order, first update after install, for whole install

 sudo apt update

 sudo apt install skype

[0chk]

Thank you. After I run

sudo apt upgrade

it told me

266 pakages can be upgraded. Run 'apt list --upgradable to see them.

.
I run

 sudo apt list --upgradable

and it showed me the list.
What do I do now?

[banceu_sergiu_ione]

You got that info after you had run apt update.
Run upgrade now

 sudo apt upgrade

[0chk]

Tahnk you. Did that, got the
E: Unable to fetch some archives, maybe run apt -get update or try with --fix-missing?
Did the:

 sudo apt-get update --fix-missing

 sudo apt update

and

 sudo apt upgrade

again and got

 E: Unable to fetch some archives, maybe run apt -get update or try with --fix-missing?

.
Again.

Your server, iq.archive.ubuntu.com, gives a lot of http 403 errors. Something's wrong with that server and that's why you cannot download the updated packages. Try switching to a different server. Go to software & updates, select download from main server or find another server that works well.
