I am making a mangos WoW auto-configuration personal script and I need libboost to compile the application as it is now a requirement. My distro is:

mangos@mangos-VB:~/Documents/setup/UbuntuBatches/MaNGOS$ uname -a
Linux mangos-VB 4.4.0-66-lowlatency #87-Ubuntu SMP PREEMPT Fri Mar 3 `16:43:09 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux`

I have the following output when tried to install it:

mangos@mangos-VB:~/Documents/setup/UbuntuBatches/MaNGOS$ sudo apt-get install libboost-all-dev

Some packages could not be installed. This may mean that you have

  • Hi, in my case "aptitude" wants to remove the "ubuntu-core-launcher" – Деян Добромиров Apr 10 '17 at 13:05
  • Please edit your question to add the output of `apt-cache policy libboost-all-dev`. And by the way, your kernel is out of date; the latest version is 4.4.0-72. Make sure you have the `linux-lowlatency` metapackage installed. – fkraiem Apr 10 '17 at 13:18
  • `linux-lowlatency is already the newest version (4.4.0.66.70).` – Деян Добромиров Apr 10 '17 at 13:27
  • [The latest version is normally 4.4.0.72.78.](http://packages.ubuntu.com/xenial/linux-lowlatency) Have you run `sudo apt update` recently? – fkraiem Apr 10 '17 at 13:31
  • Yes, it finished in seconds just now – Деян Добромиров Apr 10 '17 at 13:32
  • Maybe your mirror is out of date then, try [using another one](http://askubuntu.com/questions/682532/ubuntu-repository-change). – fkraiem Apr 10 '17 at 13:33

  • I currently got `"Main server", "Server for United states", "Server for Bulgaria"` This seems pretty obvious for me because it wants to download from a mirror which is closer, though I will suggest that the main server should be the default one to avoid such problems in the future. As it seems to download slower than before, It did not gave me this same error and started the update process. ;) – Деян Добромиров Apr 10 '17 at 13:38

Like @fkraiem said, my apt-get list was outdated, and because of that, apt could not get the dependencies in question. My update server was set to Bulgaria, because it is the closest possible one. The problem got fixed when I went to Software and updates -> Ubuntu software -> Drop down /Download from:/ -> Select /Main server/. After that Close and Reload buttons clicked. Open terminal (Ctrl+Alt+T) and enter sudo apt-get update. And voila, It's fixed !
