Thanks for the quick reply @George - that’s one step closer.
I had used dpkg -i previously, which is when I initially got the error. Based on the link you provide, I tried again using:
dpkg --force-all -i wappler_3.9.4-1_amd64.deb
Doing so let the install complete (great!), but now when I launch Wappler, it’s just a black screen:
Of course this only happens when I’m close to a release… my fault for being itchy to upgrade. I only run Wappler on one machine, so this post doesn’t seem to apply. I did try installing again, no luck.
Any ideas? Thanks for the fast responses, as always.
