I'm currently using Ubuntu 20.04 LTS. I'm having way too many issues with my computer right now, but I will start with trying to fix my WiFi. So I tried to install net-tools, but then this happened.

    patrick@patrick-Swift-SF315-51G:~$ sudo apt install net-tools

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 to be installed
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I tried this: apt --fix-broken install & apt-get -f install - received the same answer.

patrick@patrick-Swift-SF315-51G:~$ apt --fix-broken install
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

I also have received a notification from my Package Manager: The package system is broken

Check if you are using third party repositories. If so, disable them since they are a common source of problems. Furthermore, run the following command in a Terminal: apt-get install -f

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
               Depends: libc-dev-bin (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.2 is installed

So my question is, how can I fix the broken packages and use Sudo apt-get install again?

Thank you for your time.

Edit: I tried sudo apt-get clean & sudo apt-get update Then I tried Sudo apt-get -f install, same result.

E: Sub-process /usr/bin/dpkg returned an error code (1)

I also tried to sudo dpkg --configure -a; and received this

    Run that fix-broken command again, but prepend the command with sudo Jan 28, 2021 at 17:57
  • Thank you, but unfortunately, it didn't work. Jan 29, 2021 at 18:31

Try the following workflow

sudo apt-get clean

sudo apt-get update

sudo apt-get -f install

sudo dpkg --configure -a

  • I'm sorry, It just returns back to the error: Errors were encountered while processing: /var/cache/apt/archives/libc6_2.31-0ubuntu9.2_amd64.deb /var/cache/apt/archives/libc6_2.31-0ubuntu9.2_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) And when I tried dpkg --configure -a, it shows which packages are broken: dpkg: error processing package libc6-dev:amd64 (--configure): dependency problems - leaving unconfigured Processing triggers for libc-bin (2.31-0ubuntu9.1) ... Errors were encountered while processing: libc6-dbg:amd64 libc6-dev:amd64 Jan 29, 2021 at 18:25
  • It might be diffucult to read in the comment, so I will add it in the Question Jan 29, 2021 at 18:26
