Eu iniciei o Ubuntu 16.04 com o Ubuntu 14.04. Agora eu quero remover o Ubuntu 16.04. Como eu posso fazer isso? Estou tentando instalar o icinga2 no meu Ubuntu 14.04, mas ele apresenta este erro:
ruchira:~# apt-get install icinga2
Reading package lists... 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

The following information may help to resolve the situation:
The following packages have unmet dependencies:
icinga2 : Depends: icinga2-bin (= 2.5.4-1~ppa1~xenial1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
É porque eu misturei os 14.04 e os 16.04? Este problema não surgirá se eu remover 16.04?
