Suddenly, puppet agent won't run anymore on the master. I get the following error:
Info: Applying configuration version '1383770776'
Error: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install postgresql-client-unknown' returned 100: Reading package lists...
Building dependency tree...
Reading state information...
E: Unable to locate package postgresql-client-unknown
...
I really have no clue what the cause is and how to fix it. Anyone???
I tried apt-get update, didn't help.
