@advocatux The old Package link, that I send on your Request is the one for the current stable UBports, which uses an outdated Ubuntu 15.04, while the first one is for the rc and devel UBports, which use the currently supported Ubuntu 16.04. This also the reason, why both Packagelinks have a different subdomain

@advocatux According to http://old-releases.ubuntu.com/ubuntu/dists/yakkety/universe/binary-armhf/Packages.gz , vnstat_1.14-1ubuntu2 is for Yakkety Yak (aka. 16.10), while according to http://old-releases.ubuntu.com/ubuntu/dists/vivid/universe/binary-armhf/Packages.gz the Package for Vervid Vivid (aka. 15.04) is vnstat_1.12-2.

@uri Package for vivid: http://old-releases.ubuntu.com/ubuntu/pool/universe/v/vnstat/vnstat_1.12-2_armhf.deb

The corresponding package can be found under: http://ports.ubuntu.com/pool/universe/v/vnstat/vnstat_1.14-1ubuntu2_armhf.deb
