Nginx unmet depndencies?

Question

Nginx

nginx fell off out of the blue linux stopped seeing nginx - v command not found

Tried adding paths

[email protected]:~$ PATH=$PATH:~/usr/sbin
[email protected]:~$ PATH=$PATH:~/usr/local/bin
[email protected]:~$ PATH=$PATH:~/usr/local/sbin
[email protected]:~$ echo $PATH
/home/bonbon/.yarn/bin:/home/bonbon/.config/yarn/global/node_modules/.bin:/opt/gradle/gradle-6.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/home/bonbon/usr/bin:/home/bonbon/usr/sbin:/home/bonbon/usr/local/bin:/home/bonbon/usr/local/sbin

Tried to do

apt-get update
apt-get upgrade

sudo apt -o Dpkg::Options::="--force-overwrite" upgrade nginx

sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get install -f

sudo apt-get clean
sudo apt-get autoclean

sudo apt-get remove --dry-run nginx

All attempts to install on a new one, upgrade lead to an error

Judging by the strange version ( 1.18.0-4+ubuntu19.10.1+deb.sury.org+1 ) nginx was installed from some third party repository. It is worth trying to disable it and install nginx from the official debian repository.
