Upgrading packages to new version with deb no longer works
IDE 'RStudio' posts its development releases as deb files. I already have it installed, and by downloading & clicking the deb, gnome-software opens, and the green install (I think, maybe "upgrade"?) button allows me to upgrade in place, retaining settings etc.
About a month ago, maybe 2 months, this changed: gnome-software lists the version of the deb to be installed, but only gives me the option to remove, not to upgrade. E.g. new version is 1.3.1073, I have v1.3.1054 installed.
I have gnome-software v3.36.1. Bug also filed here with RStudio devs
