[18.04.4] Live system fails to reboot after installation

[Jean-Baptiste Lallement]

bionic desktop 20190122

Since bionic 20191211 the system doesn't reboot after installation.

After pressing enter to reboot, the system hangs. There is this message printed in a loop on the console:

[sdb] tag#0 access beyond end of device

(in this context sdb is the USB stick)

20191211 includes a new kernel and a new gcc

This is similar to bug 1840122 in 19.10 which started with the upgrade from kernel 5.0 to kernel 5.2. Although the error message displayed on the console was different on baremetal, it is identical in a VM.

Installing finalrd helps to work around the issue. However in Bionic, finalrd is in universe.

Diff of the manifest between last known good image and first broken image.
noticeable packages are gcc-8 and upgrade of linux 5.0 to linux 5.3

If this is indeed the same issue we saw in LP: #1840122, I think the only sane way to fix this is to proceed in the same way as we did in eoan - adding a finalrd dependency to casper. This would need pulling in finalrd into main, but I guess that was the plan already. Hopefully the MIR review should be fairy quick, as finalrd is the same across as in disco.

Let me reach out to the MIR team about this.

I'm re-using the LP: #1785267 bug for this.

So finalrd is now in main for bionic-updates. The question now is: will we need finalrd to be in bionic-security as well for this? I think we won't, but I guess my brain is a bit fried right now.

Don't see why you would. I think we just need the dependency. Thanks for
handling this!
