Rebuilding Xapian index: done.
Thank you for reply, Carlo!
I have already disabled systemd timers for APT and removed unnattended- upgrades package.
So before running Muon I have the following dates:
$ ls -lt /var/lib/ apt-xapian- index/update- timestamp /var/lib/ dpkg/status /var/cache/ apt/pkgcache. bin dpkg/status apt/pkgcache. bin apt-xapian- index/update- timestamp
-rw-r--r-- 1 root root 4812978 фев 19 01:49 /var/lib/
-rw-r--r-- 1 root root 49338939 фев 18 17:21 /var/cache/
-rw-r--r-- 1 root root 0 фев 17 22:07 /var/lib/
Then I started Muon and waited 5 minutes:
$ ls -lt /var/lib/ apt-xapian- index/update- timestamp /var/lib/ dpkg/status /var/cache/ apt/pkgcache. bin dpkg/status apt-xapian- index/update- timestamp apt/pkgcache. bin
-rw-r--r-- 1 root root 4812978 фев 19 01:49 /var/lib/
-rw-r--r-- 1 root root 0 фев 18 17:21 /var/lib/
-rw-r--r-- 1 root root 49338939 фев 18 17:21 /var/cache/
then closed Muon.
After this I have interesting process in `ps aux | grep xapian`:
/usr/bin/python3 /usr/share/ apt-xapian- index/update- apt-xapian- index-dbus
I opened Muon again, waited 5 minutes and tried to search for `scilab` - it does not return results, after closing Muon I have:
$ ls -lt /var/lib/ apt-xapian- index/update- timestamp /var/lib/ dpkg/status /var/cache/ apt/pkgcache. bin dpkg/status apt-xapian- index/update- timestamp apt/pkgcache. bin
-rw-r--r-- 1 root root 4812978 фев 19 01:49 /var/lib/
-rw-r--r-- 1 root root 0 фев 18 17:21 /var/lib/
-rw-r--r-- 1 root root 49338939 фев 18 17:21 /var/cache/
I run `sudo update- apt-xapian- index --force`:
$ sudo update- apt-xapian- index --force

Rebuilding Xapian index: done.
$ ls -lt /var/lib/ apt-xapian- index/update- timestamp /var/lib/ dpkg/status /var/cache/ apt/pkgcache. bin dpkg/status apt-xapian- index/update- timestamp apt/pkgcache. bin

So timestamp of `/var/lib/ apt-xapian- index/update- timestamp` did not change.
Started Muon again, now it is able to search `scilab` packages.
I'll try to monitor timestamps again and report back.
