Title:
Removing signed kernel installs unsigned one due to dependencies
Status in linux package in Ubuntu:
Confirmed
Bug description:
Dell XPS 15 9570. Dual boot with Windows 10. Linux was on 18.04 when
attempting to upgrade to 20.04. Had previously installed kernel
4.15-0-177 which was rolled back to working kernel 4.15-0-175 due to
issues already reported in Bug #1973482. Due to rollback, there was an
unsigned image of kernel 4.15-0-177 in the machine, which caused the
upgrade 20.04 to fail with following error. Ubuntu upgrade attempted
while logged into kernel 4.15-0-175.
