 I just did an MacPorts selfupdate.

 {{{
 $ sudo port selfupdate
 Password:
 --->  Updating MacPorts base sources using rsync
 MacPorts base version 2.9.3 installed,
 MacPorts base version 2.10.0 downloaded.

 The ports tree has been updated. To upgrade your installed ports, you
 should run
   port upgrade outdated
 }}}

 Now the port command fails no matter what command options are selected.

 {{{

 $ port outdated

 }}}

 I have done selfupdate many times in the past without issues.  Has
 something changed in 2.10.0 or are there bugs?  What database file is
 trying to be accessed?

 System: macOS 14.6.1 on MacBook Pro 2021 (M1).
