Comment 3 for bug 1612948

Got this bug on Xenial amd64 with all updates.
I have apt-xapian-index 0.47ubuntu8.3 installed.

I reinstalled python-configparser.
After editing of line 50:
change "from ConfigParser import RawConfigParser" to "from configparser import RawConfigParser" I get.

`axi-cache info` works without error,

`axi-cache search brasero` produce error:

$ axi-cache search brasero
4 results found.
Results 1-4:
100% b'brasero-common' - (unknown by apt)
