Install Muon on Ubuntu 16.04 LTS and launch it 2. Click "Check for updates" 3. Wait for "Rebuilding Search Index" to finish 4. After some time open Muon again (without 'apt-get update', 'aptitude update'). 5. Get 'Rebuilding search index' message with background process /usr/sbin/update-apt-xapian-index and high CPU load and high temperature as the result. Expected results: Muon runs update-apt-xapian-index only when it's really needed. Muon allows user to search packages instantly after launch. Actual results: Muon rebuilds search index very often and inefficient. Muon does not allow user to search packages instantly after launch. Note: This bug is very similar to the Synaptic one (see https://bugs.launchpad.net/bugs/1685376). It is caused by problems in apt-xapian-index (mainly https://bugs.launchpad.net/bugs/1612948).

Committed on 22/02/2018 at 09:27. Pushed by vanini into branch 'master'. Do not check status file for timestamp Summary: Update-apt-xapian-index is organised in plugins, each representing a data source for the index. Each of them reports a timestamp of the latest change, and the updated index takes the maximum of them as its own timestamp. We were checking the time of `Dir::State::status` (`/var/lib/dpkg/status`), which is not used in any plugin. When it was newer than all data sources, we would continuously see the index as out of date.

SUMMARY Muon rebuilds its search index almost every time it is opened, even if only minutes have passed since the last time it was in use. It also does so right after installing a package. This leaves the user unable to search for or install packages during the time the index is being updated (which for me can take up to 2 minutes at times). STEPS TO REPRODUCE 1. Launch Muon. 2. Search Index is rebuilding as indicated in the lower right corner. 3. Searching for a package yields 0 results until the index has completely been updated.
