This has been happening to me lately on various systems and with various ports, most often dbus.

Try just doing sudo port activate avahi and then select the right one (the last one) from the list that pops up. This has worked for me in every case so far.

Could you attach the log please?

This problem can't be reproduced on High Sierra. It will be very difficult to investigate further without a log or debug output.

comment:5 Changed 2 years ago by Gord-Butler

I couldn't find a log. All I got was the message stating it couldn't create a folder at the location stated in the error message.

The log path will be shown by port logfile avahi. If there isn't one then please run the command with the -d option to generate debug output.

I ran the upgrade with the -d option. This is the output.

sudo port upgrade avahi -d
--->  Scanning binaries for linking errors
--->  Found 17 broken files, matching files to ports     
--->  Found 4 broken ports, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 avahi @0.7+gtk+gtk3+quartz
 gegl @0.2.0-20180218+quartz
 opencv @3.3.1
 gmic @2.2.2

I was able to activate it with sudo port activate avahi and selecting the last option on the list, though.

Sorry, the -d needs to go between port and upgrade. Putting it at the end attempts to turn off a variant called "d".
