My build failed with the following error for some reason

I’ve changed the mirror I used but still encounters it, any ideas?
apt update runs perfectly without errors, just
snapcraft failing for some reason.
snapcraft cleanbuild with LXD containers instead
The error message seems to imply that the archive is being copied from a local file, which perhaps means the broken file was cached. Have you tried doing a
snapcraft clean first?
Well I tried
rm -r ~/.cache/snapcraft once but it didn’t work,
snapcraft clean as well.
I change the source archive to
archive.ubuntu.com, still reproduced the same issue.
Was the error still referring to tw.archive? If all mirrors have the same broken file with the same checksum, then it must be an actual bad file that was synchronized.
Nope the error referring archive.ubuntu.com instead.
Do you have a proxy setup?
No as well, just a simple NAT to the internet.
Okay, so it must be a broken file that was synchronized indeed. It should sort itself out in the next sync. The cleanbuild is likely working because it has a different configuration for apt. I doubt we have multiverse enabled by default there.
The problem seems to be solved after I remove the shouldn’t-be-available universe and multiverse components from the security.ubuntu.com archive sourceline.
Here is what’s left in the sources.list:

I still don’t know why
apt update works in the previous configuration though.
FYI, I face the same issue as well and commenting out security.ubuntu.com and bionic-proposed archives lines fixed the issued for me.
Same problem still happens on a fresh 18.04 install immediately after installing snapcraft and running it for the first time.
