Would you please run the following command for me?

sudo port clean --all mythtv-core.27 && sudo port -d checksum mythtv-core.27

Please post the output.

I've had this problem off and on where GitHub returns an archive that is somehow different from the one I got. In this case, I updated the port on September 9 and you now get a checksum error on the 25th.

[ctreleaven (Craig Treleaven)]

Thanks, but please use wiki formatting for Terminal output (code block).

I've identified what has changed to cause the checksum to fail. I've queried the MythTV developers as to why the snapshot sometimes changes. Please hold on a day or two and I'll try to get better long-term solution to this problem.

[ctreleaven (Craig Treleaven)]

Well, I'm not getting much traction with upstream. I think I have a workaround, however. Please try blacklisting github.com. To do this, edit

/opt/local/etc/macports/macports.conf

Around line 185, add the following:

host_blacklist      	github.com

Then try again

sudo port clean --all mythtv-core.27 && sudo port install mythtv-core.27

That should download an appropriate copy of the dist file from one of the MacPorts mirrors. You may want to revert your change to macports.conf if all is well.

Please let me know if this works. This problem has come up 3 or 4 times over the last 2.5 years.

ctreleaven: Is the issue a stealth update?

[ctreleaven (Craig Treleaven)]

No. Myth includes a .gitattributes file that causes another file to be updated during a git-archive operation. Which is what happens when GitHub creates a tarball from a commit hash.

Unfortunately it apparently creates different results at different times. The following shows the difference between the Sep 17 snapshot and Sep 25:

$ diff -ur prev new
diff -ur prev/MythTV-mythtv-e9b577d/mythtv/EXPORTED_VERSION new/MythTV-mythtv-e9b577d/mythtv/EXPORTED_VERSION

@@ -1,2 +1,2 @@
 SOURCE_VERSION="e9b577d"
-BRANCH=" (fixes/0.27)"

Just one line...but more than enough to mess up the checksums! I don't understand git/.gitattributes well enough to determine why. I contacted the MythTV dev who set this up (2 years ago) but he stopped responding (IRC) and I believe he is leaving on an extended trip in the near future. If you're interested, the commit is:

​https://github.com/MythTV/mythtv/commit/cc037a8804c3f260e33f5611272b192699927662

[gsulshski (Greg Ulsh)]

I completed the proposed workaround as follows:

1. update macports.conf by uncommented the host_blacklist and added github.com
2. I ran the sudo port clean and install
3. The build was successful !
4. I commented back the host_backlist and saved this version of the macports.conf
5. I re-ran port self update and upgrade outdated

It looks like it picked up all of the other updates ...apache, mysql and others so that I think I should have a full update !

I use this mac mini as a server and a home theatre setup with mythtv and kodi so this is a big deal for me !

[ctreleaven (Craig Treleaven)]

Fixed in recent update to port
