I am attempting to install php-mbstring on a Ubuntu 18.04 server which already has apache2, php and mariadb installed. I have tried with the following sequence of commands:

It appears that there is an unresolveable dependency involved. How can I correct the situation? This problem is blocking my attempt to install phpMyAdmin.

          I had to enable universe in my sources.list



          sudo vi /etc/apt/sources.list


          change the file to look like this:



          deb http://archive.ubuntu.com/ubuntu bionic main universe
          deb http://archive.ubuntu.com/ubuntu bionic-security main universe

          I had the same trouble in Ubuntu 18.04



          Edit the file /etc/apt/sources.list with the next lines:



          deb http://archive.ubuntu.com/ubuntu bionic main multiverse restricted universe
          deb http://archive.ubuntu.com/ubuntu bionic-security main multiverse restricted universe
          deb http://archive.ubuntu.com/ubuntu bionic-updates main multiverse restricted universe


          Save and run:



          sudo apt update && sudo apt-get upgrade
          sudo apt-get install php7.2-mbstring


          And it's done

          • If you're like me you might be tempted to copy those lines and update and install and move on without knowing what those things mean. I'm not sure which switch(es) made it work, so that's a little frustrating--how do I find that out? If it was restricted or multiverse do I have to pay for it? I only had "main" originally in my sources.list file. I learned: restricted=not_free/canonical_supported. universe=free/not_supported. multiverse=not_free/not_supported. en.wikipedia.org/wiki/Ubuntu#Package_classification_and_support

          • mbstring is only universe repositories so you need add multiverse, you can reach more information here: packages.ubuntu.com/bionic/php7.2-mbstring

          3














          I had the same trouble in Ubuntu 18.04



          Edit the file /etc/apt/sources.list with the next lines:



          deb http://archive.ubuntu.com/ubuntu bionic main multiverse restricted universe
          deb http://archive.ubuntu.com/ubuntu bionic-security main multiverse restricted universe
          deb http://archive.ubuntu.com/ubuntu bionic-updates main multiverse restricted universe


          Save and run:



          sudo apt update && sudo apt-get upgrade
          sudo apt-get install php7.2-mbstring


          And it's done
