There is always that possibility as it can be dependant on your experience and understanding and we can’t really know that.
But essentially it shouldn’t be a great problem. Assuming you leave some leeway between release and upgrade.
I’d tend to recommend sticking with stock updates on the OS over OBS updates.
I actually have considered Tumbleweed, but I heavily depend on running Windows in a virtualbox (ArcGIS and other simulation software) and I am not sure how easy it is to always build the kernel modules myself after each kernel update.
But Plasma 5.5.4 (and KDE Frameworks 5.19.0) will be released as official update in the standard update repo for Leap 42.1 anyway (the Plasma update has been submitted on Monday), so there’s not really a need for adding that repo.
Thanks Wolfi, that’s great news.
I might consider using tumbleweed however I checked the software OBS and saga gis and Qgis are unresolvable for tumbleweed.
I guess in that case I better stick with Leap.
