due to a misunderstanding with my co-admin, the following happend:

the trinity sources where removed in the sources.list and afterwards 2
Dist upgrades where performed:

wheezy(7) -> jessie(8)
jessie(8) -> strech(9)

now I'm unable to get rid of the installed trinity packages:

apt-get purge *-trinity
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package *-trinity
E: Regex compilation error - Invalid preceding regular expression
E: Couldn't find any package by regex '*-trinity'

But there are installled packages:
dpkg -l | grep trinity
ii  akregator-trinity                     4:3.5.13.2-0debian7.0.0+0
   amd64        RSS feed aggregator for KDE
ii  amor-trinity                          4:3.5.13.2-0debian7.0.0+0
   amd64        a Trinity creature for your desktop
ii  ark-trinity                           4:3.5.13.2-0debian7.0.0+0

ii  arts-trinity                          4:3.5.13.2-0debian7.0.0+1
   all          sound system from the official KDE release
[lots more]

Any advie, how to procede?
