Apt-get can't install anything due to broken dependencies

debian apt libc dpkg

Solution 1

I fixed it by first running

sudo dpkg -r libc6-dev-i386

then by running sudo apt-get install libc6-dev-i386.

Solution 2

I had tried the following

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get -u dist-upgrade
sudo apt --fix-broken
sudo apt-get -f install

but the problem still persisted, then this method worked for me. first: Move the /etc/apt/ folder to a temporary location [you my need Admin permission (sudo)] then run

sudo apt-get update
sudo apt full-upgrade

delete the auto generated /etc/apt/ folder then i return the previous /etc/apt/ folder back to its original location and run

sudo apt-get update
sudo apt full-upgrade

Solution 3

This usually happens as a result of 'Unmet dependencies for installed packages'

Open the terminal and run these commands in the following order:

sudo apt-get update
sudo apt --fix-broken install
sudo dpkg --configure -a
sudo apt-get clean

Whenever I run apt-get install for any package I get this error

➜  ~ sudo apt-get install clang-5.0

Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.

The following packages have unmet dependencies:

 gcc-7-multilib : Depends: libc6-dev-i386 (>= 2.11) but it is not going to be installed

 libc6-dev-x32 : Depends: libc6-dev-i386 (= 2.25-2) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

And when I run sudo apt --fix-broken install I get this error

Unpacking libc6-dev-i386 (2.25-2) ...
