Not a request for help. but just a (hopefully) helpful tip. After moving to Leap 42.3 on my mother’s computer, I could not install the scanner driver (install.sh) that I got from Epson.com. It would warn about being unsigned, then bail out before I could enter “i” to “ignore”. I installed iscan-data-1.39.0-1.noarch.rpm, then iscan-2.30.3-1.x86_64.rpm, by right clicking on each and opening in Yast (“Install/Remove Software”, in Dolphin). That allowed me to “ignore” for each, now the scanner is working. This was in KDE / Plasma, by the way. Hope this helps someone out there.
As this is not a request for help, I’ll shift it to our ‘Unreviewed How To and FAQ’ forum.
Moved from the ‘Hardware’ forum and open for positing again.
