I am currently using Ubuntu 12.04 because the latest upgrade 14.04 is not working in my system. I need to install the latest Adobe Flash Player 17 plugin, but it only allows me to install up to version 11.02, so media files cannot be opened. It says that Adobe Flash Player 17 is not compatible with my system.

This is probably actually a more general question which is : how do I see which packages will be installed when I install a metapackage? In this specific instance I have mostly only found vague descriptions like      Installing this package will pull in support for MP3 playback and decoding, support for various other audio formats (GStreamer plugins), Microsoft fonts, Java runtime environment, Flash plugin, LAME (to create compressed audio files), and DVD playback.    from    apt-get install ubuntu-restricted-extras tells me that I am installing one package: ubuntu-restricted-extras.  Especially in this case, I'd like to know what I'm putting on my computer and what agreements I am tacitly agreeing to by doing so. I'd also sort of like to know what the difference between the various *ubuntu-restricted-extras packages are.

I have installed MariaDb as its supported by Ubuntu community , mentioned in release note of latest LTS.  After that I tried to install Mariadb-client , that too installed successfully, after that its good to have GUI tool So decided to install MySql-workbench from both Ubuntu-SOftware-Center and via Terminal but it prompted errors mentioned below-  Error via Ubuntu-Software-Center-   This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.  mysql-workbench: Depends: libgcc1 (&gt;= 1:4.1.1) but 1:4.9-20140406-0ubuntu1 is to be installed              Depends: libgtkmm-2.4-1c2a (&gt;= 1:2.24.0) but 1:2.24.4-1ubuntu1 is to be installed              Depends: libpcrecpp0 (&gt;= 7.7) but 1:8.31-2ubuntu2 is to be installed              Depends: python:any (&gt;= 2.7.1-0ubuntu2) but it is a virtual package              Depends: mysql-workbench-data (= 6.0.8+dfsg-2) but 6.0.8+dfsg-2 is to be installed.   Error via Terminal-   The following packages have unmet dependencies:     mysql-workbench : Depends: mysql-client     E: Unable to correct problems, you have held broken packages.   This one has become confirmed bug on launchpad as mentioned   On the official website of My-sql , the versions of workbench are only available till saucy (13.10) , So how can I install it.   UPDATE 1  Added the following lines in /etc/apt/sources.list  # MariaDB 10.0 repository list - created 2014-04-19 11:47 UTC # http://mariadb.org/mariadb/repositories/ deb http://mirror.mephi.ru/mariadb/repo/10.0/ubuntu trusty main deb-src http://mirror.mephi.ru/mariadb/repo/10.0/ubuntu trusty main   No change , still same issue. There is some problems between trusty and version 10.1.10 of Mariadb . So tried  sudo apt-get install libmysqlclient18=10.1.10-mariadb1~trusty mysql-common=10.1.10-mariadb1~trusty   And its output is -  E: Version '10.1.10-mariadb1~trusty' for 'libmysqlclient18' was not found E: Version '10.1.10-mariadb1~trusty' for 'mysql-common' was not found   So the thing is simple it could not find it . though its there on the official website.  UPDATE 2  Removed MariaDB 10.1.10 , but the problem is still same with MariaDB 5.5.37.
