All the OS upgrades for my iMac seem to be damaged (at least that is what it is telling me when I try to open them) at the App Store. I have 2015 iMac and would like to update to Mojave OS. I'm not ready for Catalina, any suggestions?

Have you tried this one?
How to upgrade to macOS Mojave - Apple Support
Try booting into Safe Mode and download from there. Don't expect to do much of anything else while it downloads as Safe Mode is not designed to be used for much but troubleshooting.
You might also try restarting your modem and router. That sometimes helps resolve some downloading problems.
Thank you for answering and I tried your suggestions but I'm still not able to upgrade. This is what I'm seeing for High Seirra and Mojave, haven't tried Catalina because I don't want that much of an upgrade just yet :)
There are a lot of similar posts. I've never experienced that, so I'm not sure how to fix. I mentioned the few things I know to try.
Search the forums for other posts and they might have more things to try.
Thanks, I appreciate your time and help!
