--- Comment #13 from Jim JSladek@juno.com --- I checked "wine config about" on a wine 7.19 and the "wine 7.20" installation. "About" is 7.19 on the 7.19 install, but is 7.0.1 on the 7.20 install. I'll confirm that tomorrow, but it appears that wine 7.0.1 stable was put into the repo as wine 7.20 so that it was installable with the normal procedures.
Since the installed wine-mono was 7.3.0, it may not have been compatible with wine stable so that prompted the error message on the initial processing of the "update" to wine stable.
Comments 8-12 are not valid and should be deleted if that is possible. Sorry about the confusion.
