Some more interesting details, likely relevant:
The Plymouth theme named “details” stopped working for me almost four to five days ago; it was just blank. Other themes worked fine. However, hitting “Esc” when these themes showed up would again just give me a blank screen until the system booted.
That is why I tried to reinstall Plymouth in the first place, a couple of days ago and I faced this hang.
Eventually, I had to remove “quiet” and “splash=silent” and add “loglevel=3” to the kernel parameters, which brought similar details to how the “details” theme shows.
Apologies, if these details are not relevant, they appeared to me as if they are.
I would however like to know what I can do if I want to keep Plymouth.
and on reboot system will do an upgrade. For me it solved a problem. Its not recommended to use PackageKit instead of Zypper but that is only workaround I’ve found
I’ve just encountered the error from the first post for the second time this week, where the system would switch to the boot screen and zypper dup sat at
The update (or, better said, downgrade) didn’t work for me either, with the post-script stuck at 1 percent. However, stopping the Plymouth service using sudo systemctl stop plymouth-start.service before the update did the trick for me.
Didn’t see this before updating two instances of TW KDE today, finding them afterwards with the reboot screen (Plymoth), when pressing ESC had a black screen with blinking cursor.
Pulled the plug/power button and rebooted, went fine in both cases. Afterwards zypper dup shows no packages to install.
Do I need to run anything, any commands? Apparently the installs are doing fine after a hard shutdown and reboot…
To others who get stuck: ctrl+alt+del will work, and give you a relatively clean shutdown. Hit it once (don’t spam it/hold it, it’ll force the reboot) and wait a while. It’ll go.
Source: I didn’t do this the first time but reading my logs I realised I just needed to wait longer before I held it, which worked this time.
Of course, you can always lock packages, but I’m confident the update will work if you disable the Plymouth service first. Just remember to remove the package locks later if you decide to go the route to lock packages.
