I changed in yast all repositories (42.2 to 42.3 ) , and disabled the extra ones.
When it was done, I rebooted and I got the following error:
Error: symbol grub_tmp_measure not found
Entering rescue mode.
Thank god my mobo has an boot option menu. I am typing this post with an old 42.1 install of opensuse.
Pc has three harddisk., two 500 gig and a terrabyte one
Booting form one of the 500 gig ones lead to above error.
Booting from the other 500 gig one, gives me the option to boot Leap 42.1 or win 7, this is normal.
I can’t reach leap 42.2(42.3 ) the normal way, the one were the update went wrong, which is on the 1 terrabyte disk.
From leap 42.1, I do have acces to the file system of the failed update.
