I can't run apt-get commands. apt --fix-broken install doesn't work. The following packages have unmet dependencies libc6-dbg and libc6-dev

I'm new here

I have Ubuntu 18.04 LTS

When I run 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 (= 2.27-3ubuntu1.2) but 2.27-3ubuntu1 is installed
 libc6-dev : Depends: libc6 (= 2.27-3ubuntu1.2) but 2.27-3ubuntu1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Then I run sudo apt --fix-broken install

Also, in the top-right corner of the screen, a notification appears saying:

An error ocurred, please run Package Manager from the right-clic menu or apt-get in a terminal to see what is wrong. The error message was: 'Error: BrokenCount>0'. This usually means that your installed packages have unmet dependencies

And I try to install the new updates but Software Updater shows this message:

Not enough free disk space The upgrade needs a total of 107 M free space on disk '/boot'. Please free at least an additional 49.6 M of disk space on '/boot'. You can remove old kernels using 'sudo apt autoremove', and you could also set COMPRESS=xz in /etc/initramfs-tools/initramfs.conf to reduce the size of your initramfs.

And I try sudo apt autoremove

I'm sorry for the bad question, but I found the solution

When I executed sudo apt --fix-broken install, I didn't see this line:

debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable

We have to run this: sudo fuser -v /var/cache/debconf/config.dat and you'll see something like this:

                     USER        PID ACCESS COMMAND
/var/cache/debconf/config.dat:
                     root       5346 F.... frontend

And you have to run sudo kill <PID>, where PID is the number above, in this case sudo kill 5346

Finally, run sudo apt-get install -f and then you'll be able to run sudo apt-get update
