I'am using kali linux 2017.1 64 bit and I'am traying to install a certain package named lib32stdc++6 to solve the flutter compatibility issue. The problem is that apt-get install could not handle this one and I got the following output:

After this operation, 306 MB disk space will be freed.

so I tried the --fix-missing flag and I got:

I searched in the internet and stack overflow in particular and did not find an effective answer.
I found a post about installing a 32bit package on 64bit linux, it says that I should run the following commands:

dpkg --add-architecture i386
apt-get update
apt-get install lib32gcc1

Which gave me this very same output:

After this operation, 306 MB disk space will be freed.

I also checked this link https://packages.debian.org/stretch/amd64/lib32stdc++6/download and followed this instructions by add deb http://ftp.de.debian.org/debian stretch main at the and of the file /etc/apt/sources.list and run:

apt-get update
apt-get install lib32stdc

And got :

This is because Kali Linux is only for penetration purposes, not general use. See Why is Kali Linux so hard to set up? Why won't people help me?. Kali's apt is not supported by Kali's developers, which is why you encounter such errors. Please switch to another distribution which is suitable for general use (like Debian, Ubuntu, Fedora, Trisquel). Personally, I recommend Trisquel for newbies (Ubuntu if you don't want to encounter hardware issues).
