You can always run 'port rev-upgrade' again to fix errors.

Error: rev-upgrade failed: invalid command name "::registry::entry807"
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.

The rebuild of netpbm did not fail; it succeeded.

It would have been nice to see the debug output of rev-upgrade before rebuildling to know why a rebuild was necessary. Now that a rebuild has happened, we can't find out anymore.

invalid command name "::registry::entry807" sounds like a base bug. It has nothing to do with the netpbm port or any other port.

My apologies I was going by the error statement but misinterpreted it.

I will keep your comment in mind should I encounter a similar issue in the future.

Avoid using registry entries that could potentially have been
uninstalled since they were obtained.

revupgrade: avoid possible TOCTOU error

Make sure not to use registry entries after they could potentially have
been uninstalled.

These were the only cases I could find where code involved in rev-upgrade could have used invalidated registry entries in some circumstances. Unfortunately, there's not enough information to confirm that this fixes your issue. Please reopen if you find a way to reproduce the issue, and provide a log or debug output containing a traceback showing where the invalid entry is used.
