E: Some index files failed to download. They have been ignored, or old ones used instead.
Außerdem dauert es bei folgendem Repo zu lange:

Zumindest für die erste Warnung besteht die Lösung darin, die neuen GPG-Schlüssel mit dem folgenden Befehl hinzuzufügen/erneuern:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8B48AD6246925553
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7638D0442B90D010
Und was den Fehler in MariaDB betrifft, dieses Repository ist alt; Sie müssen das alte Repository entfernen. Fügen Sie den neuen GPG-Schlüssel und die neue Repository-Adresse hinzu (https://downloads.mariadb.org/mariadb/repositories/#mirror=tedeco&distro=Ubuntu&distro_release=xenial--ubuntu_xenial&version=10.2):
sudo add-apt-repository --remove ppa:http://mirrors.linsrv.net/mariadb/repo/10.0/debian/dists/wheezy/main/binary-amd64/Packages
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el]http://tedeco.fi.upm.es/mirror/mariadb/repo/10.0/ubuntuxenial Haupt'
