libxml2 version 2.7.7 install fails on checksum

[lsimmonett@…]

Libxml2 version 2.7.7 fails to install when updating or installing fresh. I have had exactly the same behaviour on version 10.6.2 and 10.6.3.

The error I get is as follows:

--->  Computing dependencies for libxml2
--->  Verifying checksum(s) for libxml2
Error: Checksum (md5) mismatch for libxml2-2.7.7.tar.gz
Error: Checksum (sha1) mismatch for libxml2-2.7.7.tar.gz
Error: Checksum (rmd160) mismatch for libxml2-2.7.7.tar.gz
Error: Target org.macports.checksum returned: Unable to verify file checksums
Error: Unable to upgrade port: 1
Before reporting a bug, first run the command again with the -d flag to get complete output.

Adding the debug -d option I get the following output:

Hope that's enough information.

Please read the FAQ on checksum errors. You did not specify the downloaded mirror.

[lsimmonett@…]

Apologies for not adding the download mirror. The mirror I have in my sources.conf is rsync://rsync.macports.org/release/ports/ This hasn't been changed since macports was installed so I assume it's the default. It is also the only mirror in that file. I'm new to macports so I hope this is what you need.

I should also add that I've tried port selfupdate and port sync, with port clean after each failed attempt. I still get the same error. Hope this helps.

[mf2k (Frank Schima)]

What you are referring to is only for the Portfiles and Portindex. The download mirror is for the actual port source code which varies depending on the port. After you run a clean --all on the port, it will show up in the fetch phase when you try to install again.

[lsimmonett@…]

The port file is fetched from ​http://lil.fr.distfiles.macports.org/libxml2 after a port clean --all. It would appear that someone has fixed the checksum issue in the last few hours as I now no longer get the error and libxml2 built and installed without issue now. It might still be worth looking into but I believe someone else has also been looking into this issue and has fixed it.

[mf2k (Frank Schima)]

Glad you got it working. The portfile - and hence the checksums in it - have not changed recently. Either the problem was on your end - i.e. a corrupt download - or you got it from a different mirror which was corrupt. The former case is most common.
