I am having a similar problem with a Canon MFP: imageRUNNER ADVANCE C3525i Using the latest Big Sur Driver for this MFP (for 11.01) on my recently upgraded system (11.1) does not work and results in this error message:
I was able to use Pacifist to force the install of the 11.01 drivers and this worked for me. Your mileage may vary, try this at your own risk. Hope this helps someone.
Following the link you provided, which was the same link I had used yesterday, there is a package for Big Sur 11.01 but not 11.1 which most everyone is on at this point. The installer for 11.01 will not install on 11.1 as stated on my OP. Is there so...
