I have been using Ubuntu 16.04. Recently I did some experiments with my PHP installation and I’m afraid I have broken things badly. I tried
sudo apt install php7.0
But it’s showing a dependency and broken package error
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: php7.0 : Depends: libapache2-mod-php7.0 but it is not going to be installed or php7.0-fpm but it is not going to be installed or php7.0-cgi but it is not going to be installed Depends: php7.0-common but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Following this, I ran
sudo apt install php7.0-common
and the response is
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: php7.0-common : Depends: libssl1.1 (>= 1.1.0) but it is not installable E: Unable to correct problems, you have held broken packages.
It seems the dependency libssl1.1
is missing so I have tried to install it manually with
sudo apt install libssl1.1
And here is the response
Reading package lists... Done Building dependency tree Reading state information... Done Package libssl1.1 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'libssl1.1' has no installation candidate
I am kinda stuck at this point. Did I break my os for good?

Answer
I have resolved the issue by installing libssl
manually.
wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb
