This morning pamac offered virtualbox-ext-oracle 6.1.36-1, so I built the package. Afterwards, Virtualbox launched, but I could not open any VM’s. Downgrade back to virtualbox-ext-oracle 6.134-1 worked as now all versions, Virtualbox, Virtualbox-guest-iso were back to version 6.134. I upgrade all to version 6.1.36 and all was working.
Please push updates Virtualbox and virtualbox-guest-iso and any others to version 6.136 in Unstable branch?
