It was all working fine but after i did sudo apt upgrade i got a red dash icon on my notification bar and started facing conflicts with python versions,

when trying :

sudo apt upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libpython3.7 : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
 libpython3.7-dev : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
 libpython3.7-stdlib : Depends: libpython3.7-minimal (= 3.7.9-1+xenial1) but 3.7.10-1+bionic2 is installed
 python3.7 : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

xenial package? grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d/ please add this to your question. — nobody, Mar 25 '21 at 08:33
Does this answer your question? How do I resolve unmet dependencies after adding a PPA? — pLumo, Mar 25 '21 at 09:22
added that output, i tried those steps from thread you shared @pLumo but it didn't work for me — bishnu das, Mar 25 '21 at 10:37
Ok, now it is clear what happened. See here same issue: https://askubuntu.com/questions/1066823/how-can-i-remove-python-3-6-installed-from-deadsnakes-ppa-after-upgrade-to-ubunt. You will need to change all 3.6 to 3.7 in the solution. — pLumo, Mar 25 '21 at 10:46
Mr pLumo, I guess after removing python3.6 i messed it up all :-| , is there anyway to reinstall distro without loosing the data? — bishnu das, Mar 25 '21 at 14:59

You have a lot of ppa's installed in your system. You should check if you still need them and consider removing at least some of them:

I see some faulty ones:

How did this artful-updates line come to your system? Remove it!
```
sed -i '/artful-updates/d' /etc/apt/sources.list
```
The gnome-terminator repo does not provide bionic sources, you have to remove it:
```
sudo rm /etc/apt/sources.list.d/gnome-terminator-ubuntu-ppa-bionic.list
```
You can simply use the one from universe repo which is already enabled.

In the end, run sudo apt update and sudo apt -f install and see if that helps.

Please refer also to this question: How do I resolve unmet dependencies after adding a PPA?

Not a problem, but you still might want to remove the .save and .distUpgrade files to clean up your sources.list.d directory:

sudo rm /etc/apt/sources.list.d/*.save /etc/apt/sources.list.d/*.distUpgrade

gnome-terminator is the shell i use, first one i dont know about it — bishnu das, Mar 25 '21 at 10:36
The shell is probably bash or so, you mean terminal. It's fine to use terminator, but this repository cannot be used for it. It is however in universe repository which you have already enabled — pLumo, Mar 25 '21 at 10:41
