I tried updating from 25 directly to 27 and after:
sudo dnf system-upgrade reboot
it restarted and hanged somewhere.
Now I'm stuck with this screen:
I tried upgrading from 25 to 27 directly because a colleague assured me he did the same and it work.
First question is this kind of upgrade available in Fedora? Or it's more likely that he had 26 and thought that he had 25?
I can't access the command line. I tried editing the grub file at startup by adding a 3 as the last argument to the linux command - didn't work.
Second question: can I recover the system from here? Or at least recover the data from the hard disk? (hard disk is encrypted)
