install postgresql on ubuntu 19.10 - postgresql

I'm trying to install postgresql on ubuntu 19.10 (Eoan). I've tried many ways but it seems that even the newest version of postgresql (12) is not supported.
Does anyone know if it can be installed in some way?
this is the error I get when I'm trying to install, for example, postgresql 11:
$ sudo apt-get install postgresql-11

I tried installing libssl1.1 package using apt but I was unable to do so it throws following error.
E: Package 'libssl1.1' has no installation candidate
please someone help.
It seems mongodb require specific version of libssl1.1
you can download debian file of that version and install using following commands. Most probably it will resolve this issue.
sudo wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb
After hours of looking for a solution I was satisfied with, I finally stumbled across one! Hope this helps anyone else looking to install MongoDB community edition without sacrificing security by using libssl1.1 (the solution here uses >3.0.
MongoDB has the repository for Ubuntu 22.04.1 LTS (Jammy Jellyfish) hidden away. It definitely still isn't on the documentation installation pages as of the time I am posting this. Check it out yourself: https://repo.mongodb.org/apt/ubuntu/dists/jammy/mongodb-org/
The following code will add the repository and install the latest mongodb-org on your system:
sudo apt-get install wget gpg
wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | gpg --dearmor > packages.mongodb.gpg
sudo install -D -o root -g root -m 644 packages.mongodb.gpg /etc/apt/keyrings/packages.mongodb.gpg
echo "deb [ arch=amd64,arm64 signed-by=/etc/apt/keyrings/packages.mongodb.gpg] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list
rm -f packages.mongodb.gpg
sudo apt-get install -y mongodb-org

unfinished installation of pgadmin4 keeps blocking other installations

I have been trying to install pgAdmin4 but I get this error below, I tried to resolve the error and I couldn't, so I decided to go on with my installations, then I tried Mongodb, it also can't install
sudo apt-get install -y mongodb-org=4.4.2 mongodb-org-server=4.4.2 mongodb-org-shell=4.4.2 mongodb-org-mongos=4.4.2 mongodb-org-tools=4.4.2

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org-tools : Depends: mongodb-database-tools but it is not going to be installed
Depends: mongodb-org-database-tools-extra but it is not going to be installed
pgadmin4 : Depends: pgadmin4-web but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I have tried:
sudo apt --fix-broken install
but still no positive yields as the error persists
How can I fully remove pgAdmin, I mean anything related to postgres, so that I re install a new fresh bundle.
The problem was with my dpkg config. but this helped me out

Error installing mongodb , broken ubuntu dependency

Trying to install mongo with below command

mongodb-org is already the newest version (3.6.2).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mongodb-org : Depends: mongodb-org-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I had this same issue installing mongodb-org on an Ubuntu 18 box.
The issue was that a version of mongodb was already installed, and it had to be removed before I continued.
The solution was to run the following:
sudo apt remove mongodb-org
sudo apt purge mongodb-org
sudo apt autoremove
sudo apt-get install mongodb-org
More info can be found on the Mongodb website - apparently this is a frequent enough issue that they had to address it there!

Cannot install latest Mongdb

My production Mongo database was hacked and all databases deleted. I now want to upgrade to the latest version of Mongo but am having extraordinary problems. Im on Linux Mint 17.1. Im following instructions here:
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/
When I run:
sudo apt-get install -y mongodb-org
I end up with error:
Reading package lists... Done

What can I try next? As I said, my app is down since the hack and now I cannot even install Mongo...
Try sudo apt-get install -f to fix packages.
If that doesn't work, figure out if you need all 4 packages, mongodb-org-server might be the only one you really need.
In this case you can try running the following command with a specific version (3.0.15 in my case):
sudo apt-get install -y --force-yes mongodb-org=3.0.15 mongodb-org-server=3.0.15 mongodb-org-shell=3.0.15 mongodb-org-mongos=3.0.15 mongodb-org-tools=3.0.15
