Update Disabled YAST

English Install/Boot/Login
#1

Just updated Tumbleweed on a multi-boot system: Win 10, Linux Mint 17.3. As has happened before, updating Tumbleweed erases the GRUB listing of the other OS’s. My usual fix is to run YAST - System - Boot Loader and that restores the boot menu with the other OS’s.

But this update has also killed YAST: running it reports
what(): Couldn’t load plug-in qt
/sbin/yast2: line 448: 2346 Aborted
(core dumped) $ybindir/y2start $module “$@” “$SELECTED_GUI” $Y2_GEOMETRY $Y2UI_ARGS

Another major breakdown after an update required running zypper dup, but that reports

Solution 1: keep obsolete graphviz-gd-2.38.0-140.63.x86_64

Choose the above solution using ‘1’ or skip, retry or cancel [1/s/r/c] (c):

Solution “1” does not work: spews out a long list of conflicting packages.

Update: at least I was able to restore my boot loader menu so I can boot the other OS’s: "grub2-mkconfig -o /boot/grub2/grub.cfg

This fix was found in a text file in /boot.

But YAST is still broken and completely nonfunctional. The app opens but none of the subroutines will execute.

#3

Try this from the terminal

sudo zypper up libyui-qt-graph8 libyui-qt-pkg8 libyui-qt8
#4

Didn’t work:

 linux-agai:~ # sudo zypper up libyui-qt-graph8 libyui-qt-pkg8 libyui-qt8

That did it! Thanks!.
Now for the “why” this break down occurred.

I run an old laptop with Mint 17.3 and Tumbleweed. Tumbleweed’s GRUB does the booting. I had not run the update on this system yet, so I installed the above packages first.
The update installed, and as has become the norm, it erased Mint from the boot list. But this time I was able to run YAST > System > Bootloader without any problems.

#8

I had this problem too. Thanks for the fix.

#9

I just updated with kernel 4-12-7-2. This time the boot menu remained intact. Now I’m wondering if these packages, or rather, their absence, was causing the boot menu to lose its other listed OS’s after almost every update.

I noticed several reports in another forum along the same lines. V_idocq’s tip has helped a number of users. Molto grazie!
