I am trying to install the following packcage postgresql-server-dev-9.5. Using
sudo apt-get install postgresql-server-dev-9.5
Now, after I run this command I get this error:
Unable to locate package postgresql-server-dev-9.5.
Couldn't find any package by glob 'postgresql-server-dev-9.5'.
Couldn't find any package by regex 'postgresql-server-dev-9.5'
How can I fix this? I use ubuntu 18.04.1
