I had encountered a similar problem before, and was able to work out a – rather convoluted – workaround..<\/p>\n
In this upgrade, the F27 rpms are resident at \/var\/lib\/dnf\/system-upgrade<\/strong><\/span> , and each repo has its own sub-directory – the repo ID followed by a uuid-style numerical string, eg:\u00a0 fedora-cba4cf65782eccda<\/span><\/strong> , updates-09879b494aeba108<\/span><\/strong> ,<\/span> rpmfusion-free-093775106f01a54b <\/strong><\/span>etc..\u00a0\u00a0\u00a0 In each of these, the F27 upgrade rpms – if there are any – are in the packages<\/strong><\/span> sub-directory..\u00a0 If there are no upgrade rpms for a particular repo, then the packages<\/span><\/strong> sub-directory will not exist..
\n<\/span><\/span><\/p>\n
As root, I created a temporary directory and copied each group of F27 rpms to this, so that the update\/upgrade could be done all-at-once..\u00a0 Then I checked for the kernel….xxx rpms, and installed<\/span> (not updated!) these by # rpm -ivh kernel*rpm --nodeps --force<\/code><\/strong><\/span> , and then deleted<\/span> them..\u00a0\u00a0 After that, I updated<\/span> all the remaining F27 rpms:\u00a0 # rpm -Uvh *rpm --nodeps --force<\/code><\/span><\/strong> , and waited for this to complete (which takes some time!).\u00a0\u00a0\u00a0\u00a0\u00a0 After that, I simply re-booted the system, and it came back up – correctly – as Fedora 27.<\/p>\n
