Hello.
I'm currently on mac OS Mojave 10.14.6 and trying to update to Catalina. When I hit update from App Store Catalina after 10 minutes I get this error
I tried everything I found on the internet regarding this error but could not get it to work ( reset SMC, disable auto proxy, try from another admin user, try in safe mode etc etc ) . What should I do?

Hi georgemihoc,
Thanks for reaching out here in the Apple Support Communities. I understand that you're getting an error while trying to install macOS Catalina.
I'm glad to help with this.
I suggest that you try to install macOS Catalina from macOS Recovery: How to reinstall macOS from macOS Recovery
I also recommend, if you haven't done so already, to make a backup of your Mac so that your files will be safe: How to back up your Mac
Best Regards.
Do you have a backup of your Mac as mentioned above? If yes, did you try the erase alternative from the link posted above How to reinstall macOS from macOS Recovery? Here it is:
2. Decide whether to erase (format) your disk
You probably don't need to erase, unless you're selling, trading in, or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Learn more about when and how to erase.
Ok so I just tried to erase the disk and install after.
First, I erased OS X disk and tried installing Catalina from recovery , no success.
Then, I tried installing Catalina from usb, no success either.
Both times same error, could not install.
Do I have any other options for updating?
A reply of mine, about Bootcamp, ended up not being posted somehow. I think you
are out of options unless you are not using Ethernet to install. I doubt it will make a
difference, but you can give using Ethernet a shot if you are not already doing so.
Hello,
Thanks for your answer. I've just tried to install Catalina from macOS Recovery but still the same error...
What can I do?
Yes, I do have a backup.
My concern regarding this is that I have a windows partition in Bootcamp. Erasing the OS X disk and installing Catalina afterwards will affect the bootcamp partition?
