Install Software Properties
sudo apt install software-properties-common

It looks as though something has replaced the version codename incorrectly in your apt source files (i.e. /etc/apt/sources.list and the other files in /etc/apt/sources.list.d/)
It is likely that some instructions you followed to add a PPA inadvertently caused this, or one of the packages you installed from one of those PPAs did this automatically.
If you are ...

I found out that you can get back the update manager by installing software properties:
sudo apt update
sudo apt install software-properties-gtk
This will allow you to choose the sources and servers, just like in freya and Ubuntu.
EDIT: I wasn't precise since the update manager is another application - known from freya and taking care of system and ...

Did you install cdrom://elementary OS 0.4 _Loki_ - Stable amd64 (20160921) as a repository? See if it's listed with grep ^ /etc/apt/sources.list /etc/apt/sources.list.d/*
If so, you want to remove it. If you are attempting to upgrade to Loki, you'll need to do a fresh install from boot (not an upgrade). There are installation directions on the official ...

Everything you need is already inside /etc/apt/sources.list.d/ and /etc/apt/sources.list.
You don't need any extra PPA. If you want some interesting programs you can check the following:

Sometimes the regional mirrors can have issues. Davin Miler is correct, have patience and try again, but alternatively, you can use another mirror (you are using tr.archive.ubuntu.com)
Open your sources.list file using your favorite text editor, e.g.
sudo nano /etc/apt/sources.list
Locate the text http://us.archive.ubuntu.com/ubuntu and replace it

Yes, it does update packages from PPAs too.

Ok, found the culprit.
Just noticed my clock was wrong.
Now everything is working again...

If you don't know where to begin, try the developer guide they provide, it helps a lot.
Unfortunately developing an OS don't work this way, you have to start a issue on launchpad or github (depending on the project you are working on), with the reasons why this feature should be implemented. If the team is OK with your feature you can start to code it, then ...

This worked perfectly:
apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install bitcoin-qt

Your issue seems to be caused by some obsolete / wrong repositories.
First one (http://ppa.launchpad.net/djart/minidlna/ubuntu) was not updated since 2014, and using it is a really bad idea. You can remove it safely with:
sudo add-apt-repository --remove ppa:djart/minidlna
For the next ones, you'll have to do some source.list editing, because they contain ...

Not yet.
All curated apps for AppCenter are currently built as .deb packages. There is a plan to work on moving them all to Flatpak. But this work hasn't been completed yet, mostly due to the fact that there was a team due to go and work on this in person, but it got delayed due to Covid-19.
So there's no definitive date yet of when this will be available.

The main repository file is /etc/apt/sources.list and the sources you add usually go there as lines or into /etc/apt/sources.list.d/ folder as *.list files. I do not know your linux and terminal skills but you can edit the above file using terminal.
If you attempt to do this, do a backup of the file first, for example into your home folder with sudo cp /...

So the solution was pretty simple. Just a matter of removing AppCenter:
sudo apt remove appcenter
and then reinstalling it
sudo apt install appcenter
Et viola, no more errors! I think it had something to do with reusing a /home partition from a previous elementary OS (and a few other distros too) install.

The repository 'http://ppa.launchpad.net/versable/ is a supplementary PPA for older versions of elementary OS (Luna, as stated on the PPA's page). However, when your system tries to get updates from this PPA, it can't find release files for your OS version there. Possible solutions:
remove this supplementary (obsolete?) PPA from your system list:
sudo ppa-...

It looks like AppCentre can't handle that kind of user interaction
That message was a normal user interaction asking if you accept the change from Google Inc to Google LLC in the repo's config
Anyone using apt through terminal could answer that without any issue but if the GUI, in this case AppCentre, wasn't able to and by default treated like an error you ...

Change in /etc/apt/sources.list.d/appcenter.list
http://packages.elementary.io/appcenter juno main
to
http://packages.elementary.io/appcenter bionic main
(juno -> bionic)
From https://elementaryos.stackexchange.com/a/16889/14940
After checking every repository online, I fixed the issue by replacing juno with bionic in the below files:
/etc/apt/...

It looks like there are two different errors here:
The first is that it looks like the AppCenter has been added twice. I'm not sure what has done this, but apt doesn't handle the same repository being configured twice very well. It's configured once in /etc/apt/sources.list on line 56. And once in /etc/apt/sources.list.d/appcenter.list. The original/correct ...

After Researching all day i finally found the answer. I hope this helps someone..
First open "Software & Updates" and click on the "Other Software" tab for my issue, The box at the top named "cdrom:[elementary OS 0.4.1 Loki-Stable amd64 (201880214)]/xenial" was "checked" or selected and it shouldn't have been. i unchecked and it was fixed.

I think the problem is the 'loki' part of 'https://s3-us-west-2.amazonaws.com/brave-apt loki Release'. Loki is the name of the latest Elementary OS release.
This happens because lsb_release -sc in the commands they instruct you to use returns the text "loki".
You can try this by running:
echo `lsb_release -sc`
The install instructions are for Ubuntu and ...

According to the official docs of the Brave browser you can install it via apt-get after adding the repository to your sources list:
curl https://s3-us-west-2.amazonaws.com/brave-apt/keys.asc | sudo apt-key add -
echo "deb [arch=amd64] https://s3-us-west-2.amazonaws.com/brave-apt `lsb_release -sc` main" | sudo tee -a /etc/apt/sources.list.d/brave-`...

I once had similar problem - my sources where somehow wrong.
Here were the correct ones for LOKI that solved it for me:
sudo scratch-text-editor /etc/apt/sources.list.d/appcenter.list
and there...
deb http://packages.elementary.io/appcenter xenial main
...next...
sudo scratch-text-editor /etc/apt/sources.list.d/elementary.list
and there
deb http://ppa....

There isn't xenial release to that PPA. You can find the accepted releases at
Versable PPA dists
If you want to install Elementary Tweaks you can try:

Just wait, the error will be fixed soon

Found the solution!
https://wiki.ubuntuusers.de/Canon_UFRII/UFRII_LT_Druckertreiber/
This was the line, that solves the printing problem:
sudo apt-get install lib32stdc++6 libxml2:i386

Clean your cache and try again:
sudo apt clean
sudo apt update
sudo apt upgrade
If that isn't enough, try removing any offending repositories from Applications menu > Software & Updates. (If you need to install that, use sudo apt install software-properties-common.)
