Bug#821792: apt-xapian-index: update-apt-xapian-index (called by cron.weekly) fails with a python 2.7 decode() error

[Uwe Bolick]

Hi,

I was hit by the same problem.

I solved my problem by commenting out
  Acquire::GzipIndexes "true";
in /etc/apt/apt.conf.d and uncompressed all files (.gz, .bz2, .xz) in
  /var/lib/apt/lists
  
It seems that apt-xapian-index is not able to handle compressed files.

Greetings,

Uwe
