Public bug reported:
The build script does not install package updates during generate the
pc-kernel snap.
I met this bug #1783810 when I was verify my Ubuntu Core 18 image on KVM.
The system stuck at resizing the writable partition. the resize script of
initrd called sgdisk to achieve the resizing. Inside sgdisk, it use libuuid1 to
get random bytes and generate UUIDs. After I extracted the kernel snap, I found
it is still using libuuid1 2.31.1-0.4ubuntu3 which is not the latest version.
At this moment, Bionic has 2.31.1-0.4ubuntu3.2.
Then I added commands to make the build script installing package updates.
After that, the system can boot correctly without any problem.
I am wondering if there is any concern to pull updates before building?
The attachment is my patch to pull updates.
