For what it's worth, the Marion County (Indianapolis) Civil Sheriff's Office announced last week that its May 2020 sale has been cancelled.  (The sheriff previously cancelled the April sale.)  The email from Marion County indicated that the June 2020 sale is still a go - at least for now.  The Marion County situation seems to be consistent with both our Governor's order and the CARES Act, Sections 4022 and 4023, to the extent those apply to a particular case.  

Always remain mindful that, although the Indiana Code covers the fundamentals of the sheriff's sale process, the specific procedures vary by county.  Local rules, customs, and practices control.  There is a saying in Indiana that there are 92 counties and therefore 92 different sets of rules applicable to sheriff's sales.  My point is that, if you have questions, you should call the local civil sheriff's office to confirm the status of its foreclosure sale activities (publications, notices, sales, etc.)  during the COVID-19 pandemic.
