Comment 30 for bug 1746807

TLDR: try rebuilding the iso downgrading the four packages /pool/main/a/apt/*.deb to 1.6~alpha 5?

Note: I pasted the info backwards...it's 1.6~alpha 5 that's the good version.

As a test...I tried manually downgrading apt*.deb on-the fly:

I created a virtual machine with a second (empty) cdrom drive. Once I got the missing kernel:

I switch to alternate terminal..
chroot /target

"apt-cdrom add" gives same error...

Mounted the GOOD 20180131 iso into the vm as the second cdrom.
mkdir /blah
mount /dev/sr1 /blah
cd /blah/pool/main/a/apt
dpkg -i *.deb
cd /
umount /blah

i.e. force load previous apt and apt-cdrom packages.

apt-cdrom

This no longer gives the error.

Just as a test...

cd /media/cdrom/pool/main/a/apt <-- original bad cdrom
dpkg -i *.deb

i.e. force load bad apt/apt-cdrom packages from latest 20180216

apt-cdrom

This gives the stat no such file or directory error.

So...downgrading the four packages /pool/main/a/apt/*.deb should work around the issue?
