[FIXED BUG] Cannot update Plesk with KernelCare extension installed: /lib/modules/3.14.32-xxxx-std-ipv6-64: No such file or directory

Symptoms

1. Cannot update Plesk: update fails on KernelCare extension.

2. Errors in /var/log/plesk/install/autoinstaller3.log:

   CONFIG_TEXT: E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
   E: Unable to lock directory /var/lib/apt/lists/

   CONFIG_TEXT: Setting up kernelcare (2.14-11) ...
   depmod: ERROR: could not open directory /lib/modules/x.xx.xx-xxxx-std-ipv6-64: No such file or directory
   depmod: FATAL: could not search modules: No such file or directory
   dpkg: error processing package kernelcare (--configure):

3. /lib/modules directory is absent

   # ls -ld /lib/modules
   ls: cannot access /lib/modules: No such file or directory

4. KernelCare is half-configured and "apt-get install -f" command fails to complete configuration:

   # dpkg -l kernelcare
   iF  kernelcare       2.14-11 amd64         Tools for KernelCare

5. Repetitive attempts to configure kernelcare package can be found in /var/log/dpkg.log:
