As I see my problem is similar to this one libc6 dependency mismatch in Debian 9.12 stretch. Please,advice a solution for my distribution

sudo apt-get upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libc6-dbg : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.1 is installed
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.1 is installed
 libc6-i386 : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

sudo apt install --fix-broken

looks like you have at least this problem: https://askubuntu.com/questions/136881/debconf-dbdriver-config-config-dat-is-locked-by-another-process-resource-t once you have fixed that try installing again, might work already.

shortfix (but maybe dangerous) check for running apt, dpkg processes, if not you may have to decide try reboot and run apt install which will mostly not work or delete the lock file and run then the apt install this time it may run

Don't find similarity. Output in my case: sudo fuser -v /var/cache/debconf/config.dat USER PID ACCESS COMMAND /var/cache/debconf/config.dat: root 7573 F.... frontend Why should I kill that. Please, explain

The similarity is that you have another process ruining and holding the lock on `/var/cache/debconf/config.dat` which prevents you from running `apt` commands.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
