It might be related under the hood. Did you write to your linux partition
from MacOS some time before the failure?

Weird. Did something change at the kernel level? Did you enable/disable
some security stuff (SMACK) ?

There's /var/log/dpkg.log but I saw your apt-history file and I don't
think the supplementary packages can explain why it works now. It's more
a kernel level issue or maybe a glibc issue. Somehow I would favor a bug
in the kernel with ext2 possibly related to some unexpected stuff done
by MacOS. But it's just a wild guess. It might also be some issue with
SMACK or similar security modules but I doubt we would get EINVAL as error
code if that was the reason.
