How to upgrade ubuntus package?
I was install Nginx and MariaDB using default ubuntu repository few month ago.
and i want to upgrade nginx or mariadb more lastest version using another PPA.
Is it ok just add lastest PPA (like deb http://ftp.osuosl.org/pub/mariadb/repo/10.1/ubuntu trusty mainand) and then apt-get install update && upgrade?
or need to uninstall Nginx and Mairadb after, just install new version?
