Unable to uninstall snapd 2.34.2 in 16.04

Question

I've been having problems with upgrading snapd with apt-get. I've tried running dpkg --configure -a and sudo apt-get install -f, but the system hangs indefinitely setting up snapd. I've also read numerous posts on how to resolve this issue, but unfortunately none of them have worked. Some posts seem promising, but my main problem is that I cannot uninnstall snapd because the subprocess new pre-removal script returned error exit status 1. Right before this error message, the system says the job for snapd.service and snapd.socket have been canceled. I have tried everything I know to try, and searched around the net, but would appreciate some insight from you all about this issue!

So far, I have tried: sudo apt purge snapd and sudo apt purge snapd ubuntu-core-launcher squashfs-tools, but I get the same results.

Try this sudo apt purge snapd ubuntu-core-launcher squashfs-tools seen here https://ubuntuforums.org/showthread.php?t=2328152 — George Udosen, Jan 02 '19 at 22:15
Stop it first with sudo systemctl stop snapd then disable sudo systemctl disable snapd then try to remove it! — George Udosen, Jan 02 '19 at 22:19
Unfortunately, I still get the same result even after stopping and disabling snapd. — myselfesteem, Jan 02 '19 at 22:33
Lets try this. Please update and upgrade your system then try again for this is indeed a strange behaviour! — George Udosen, Jan 02 '19 at 22:36
Right, updating works fine, but when I upgrade, it gets stuck on "setting up snapd", which is what caused this mess lol. — myselfesteem, Jan 02 '19 at 22:38
Please look at the methods here lets re-install then see if the upgrade will work https://askubuntu.com/a/1050466/459561 — George Udosen, Jan 02 '19 at 22:43
I'm working on reinstalling snapd, but I think your previous advice may have messed things up because when I do sudo apt install --reinstall snapd, I get: Internal Error, No file name for snapd:amd64 — myselfesteem, Jan 02 '19 at 22:58
I've enabled snapd, and tried to reinstall it, but there's No file name for snapd:amd64 again — myselfesteem, Jan 02 '19 at 23:08

Just to add more flesh to George's answer. I needed to

cd /var/lib/dpkg/updates/
sudo rm *
sudo fuser -vki /var/lib/dpkg/lock (bc there was a lock on dpkg process)
sudo systemctl stop snapd (stop the snapd process..if it's running)
sudo rm -f /etc/apt/sources.list.d/* (solves: Internal Error no file name for snapd:amd64)
sudo apt purge snapd ubuntu-core-launcher squashfs-tools

I'm not sure if steps 1) and 2) are necessary, but at the end of the day, this is what worked for me. I'm not sure, but could my system still reinstall snapd when I do sudo apt-get update/upgrade?

Ok that it finally worked, run that update and upgrade command and let us know! – George Udosen Jan 03 '19 at 06:33
