Unmet dependencies and broken packages after installing libstdc++6

When trying to use screenshare with audio on vesktop, I got an error from the app that read "your c++ library is too old to run venmic", which prompted me to try and update it. I followed the steps: sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update sudo apt-get install --only-upgrade libstdc++6 **I also updated my gcc through the software manager right after**. The packages that were removed from these commands were: intel-media-va-driver:i386 libgl1:i386 libgl1-mesa-dri:i386 libglx-mesa0:i386 libglx0:i386 libicu70:i386 libigdgmm12:i386 libllvm15:i386 libnvidia-fbc1-535:i386 libstdc++6:i386 libva-glx2:i386 libxml2:i386 mesa-va-drivers:i386 mesa-vulkan-drivers:i386 steam:i386 steam-libs-i386:i386 va-driver-all:i386 I didn't think much of it since it was getting replaced by other libraries, sadly I don't remember which ones, though I didn't notice the "nvidia-firmware" or "steam-devices" packages. I also thought that it would be simple to undo this procedure afterwards so I kept it going. Vesktop was working afterwards but some other apps were not, so I then tried undoing it by reinstalling all the removed apps, assuming it would remove the libstdc++6 and replace it with a different one. Here's what happened: sudo apt install intel-media-va-driver:i386 libgl1:i386 libgl1-mesa-dri:i386 libglx-mesa0:i386 libglx0:i386 libicu70:i386 libigdgmm12:i386 libllvm15:i386 libnvidia-fbc1-535:i386 libstdc++6:i386 libva-glx2:i386 libxml2:i386 mesa-va-drivers:i386 mesa-vulkan-drivers:i386 steam:i386 steam-libs-i386:i386 va-driver-all:i386 Reading package lists...

I then noticed that Steam was gone from my apps, and when trying to install it again, I ran into an error as well: The following packages have unmet dependencies: apt: Depends: libapt-pkg6.0 (>= 2.4.12) but it is not going to be installed Depends: libstdc++6 (>= 11) but it is not installable mintsources: Depends: python3-apt but it is not going to be installed Depends: python3-gi but it is not going to be installed Depends: python3-gi-cairo but it is not going to be installed Depends: python3-pycurl but it is not going to be installed Depends: python3-requests but it is not going to be installed Depends: mint-common (>= 2) but it is not going to be installed Depends: gir1.2-gdkpixbuf-2.0 but it is not going to be installed Depends: gir1.2-gtk-3.0 but it is not going to be installed Depends: gir1.2-vte-2.91 but it is not going to be installed Depends: gir1.2-xapp-1.0 but it is not going to be installed Depends: lsb-release but it is not going to be installed So what happened and what do I do? I've never had this problem before, and I've used outside repos before. I haven't run the autoremove command out of fear of breaking things further, but it seems like those packages are the ones causing problems. I'm running Linux Mint 21.1 and I'm not sure which c++ library is the proper one for this system, I'd just like to get things back to how they were. **The apt policy command for libstdc++6 and libstdc++6:i386**: apt policy libstdc++6 libstdc++6:i386 libstdc++6: Installed: 13.1.0-8ubuntu1~22.04 Candidate: 13.1.0-8ubuntu1~22.04 Version table: *** 13.1.0-8ubuntu1~22.04 100 100 /var/lib/dpkg/status 12.3.0-1ubuntu1~22.04 500 500 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages 12-20220319-1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages libstdc++6:i386: Installed: (none) Candidate: 12.3.0-1ubuntu1~22.04 Version table: 12.3.0-1ubuntu1~22.04 500 500 http://archive.ubuntu.com/ubuntu jammy-updates/main i386 Packages 500 http://security.ubuntu.com/ubuntu jammy-security/main i386 Packages 12-20220319-1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu jammy/main i386 Packages
