Today I am doing maintenance of the server Debian 8.4, and I don't know why phpmyadmin package has been held back, well I haven't solved such situation yet, so any suggestions are welcome, thank you.apt-get upgraderoot@vb-srv-debian:/# apt-get upgradeReading package lists...

phpmyadmin held back, why and how to fix it?
apt;phpmyadmin
You're pulling in phpmyadmin from a Trusty PPA. The package there seems to be a straightfoward rebuild of the phpmyadmin package in Debian, but the latter recently changed to simplify its dependencies, using the new php-defaults packages. The resulting package can no longer be installed in Debian 8.There is no easy solution to upgrade to version 4.6.1 of the Debian/Ubuntu packages. Typically I would recommend using the Jessie version (which gets security support), but downgrading phpMyAdmin might not be easy either (or possible at all)... You could always ask for a backport.
