System Info: Ubuntu 20.04.3 LTS 64bit, gnome 3.36.8, windowing system X11 RAM 15GB, SSD 500GB, Intel i5

Just installed synaptic but could not run it. I am not sure why it kept looking for libxapian.so.30 when there is libxapian.so in /usr/lib/x86_64-linux-gnu folder. Also why libxapian.so is appended with ".30".

Kindly help me fix it. I am posting this for synaptic but this is happening with almost all newly installed apps.

You have to reinstall the proper library from official Ubuntu package by using commands below:

sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install --reinstall libxapian30 libxapian-dev

and then retry running Synaptic.

  • Thanks buddy, it fixed the issue. Actually I accidentally removed /usr/lib/x86_64-linux-gnu folder. to resolve this I copied same folder from liveusb drive. probably because of this libraries are missing. Is there any way to list all missing library and than download them? – Pankaj Patel Oct 17 '21 at 14:04
