All system documentation suddenly disappeared

I seem to be suffering this too. yelp says this too on the command line:
I/O warning : failed to load external entity "Cannot write to log file: /var/log/scrollkeeper.log : Permission denied"

I can confirm this as well with today's build

one task is enough

That issue happens when some package ship the autogenerated by mistake. When the app is fixed, dpkg clean them on upgrade because they were shipped by the package. Ekiga package had that issue and that's fixed now. People having their index broken can run "sudo scrollkeeper-rebuilddb" to fix it. I'm marking the bug as fixed since it was a transitionnal bug on a unstable distribution, the package causing it is fixed. Feel free to reopen if you disagree

Thanks a lot, that fixed the problem.

Hmmm, not for me. "sudo scrollkeeper-rebuilddb" immediately exits without doing anything. Adding the -v option doesn't produce any output either, and /var/log/scrollkeeper.log is empty.

Yelp is still empty too.

Yelp also prints "Cannot write to log file: /var/log/scrollkeeper.log : Permission denied" on the cmd line.

The permissions of the log are -rw-r--r--, root root

Mario, you have a different issue, please open a different bug. The permission denied has already a bug for it

I/O warning : failed to load external entity "Cannot write to log file: /var/log/scrollkeeper.log : Permission denied"
, is what I get.

'sudo scrollkeeper-rebuilddb' works for me. locale :
