Kubuntu dev request: integrate QApt index with apt-get

[SteveRiley]

I can't create the file.

Hmm.... the directory /etc/apt/apt.conf.d/ should exist on your system. Can you verify?

[SteveRiley]

I don't know the meaning of this

The repositorites contain translation files. Both Apt and QApt need these. Those extra lines are the output of the Xapian indexer reading the translation files for QApt.

PS my output looks diferent than yours SR ,,,will reboot and test one more time and look for a change.

Vinny, it appears that you ran apt-get upgrade rather than apt-get update.

I can't create the file.

I don't know the meaning of this ...

Neither do I, but the developers do, and that is why we who volunteered added that script.

In our little corner of the Linux desktop world, we have two package management indexes. One is maintained by Apt (apt-get, apt-cache, dpkg, and related). The other is mainted by QApt, an abstraction layer for Apt that's integrated with Qt and KDE applications -- Muon being the prime example.

In a recent email to the kubuntu-devel list, Harald has asked for some help with a small but important test: invoking the QApt indexer, called Xapian, whenever apt-get update successfully runs. It's easy to do:

1. Run your favorite text editor as root and create the file /etc/apt/apt.conf.d/90xapian

2. Paste the following line into the file:

APT::Update::Post-Invoke-Success { "if [ -x /usr/sbin/update-apt-xapian-index ]; then update-apt-xapian-index -u; fi" }

3. Save the file and exit the editor

When you run apt-get update, you'll see something like:

...
Fetched 85.7 kB in 20s (4,196 B/s)
Reading .desktop files from /usr/share/app-install/desktop/: done.  
... }
... } [i]several lines of reading translation files[/i]
... }
Reading Xapian index: done.  
Updating Xapian index: done.  
Reading package lists... Done

It will likely increase the run time of apt-get update by only a few seconds.

The test is to help gather information for determining whether to make this a Ubuntu-wide change for 15.04. It's an easy thing to do, won't harm your system, and helps improve package management and stability.

If you encounter issues, report back here or (better) subscribe to kubuntu-devel and reply to Harald's message.
