When trying to clone release-cesm2.1.3 there is an error due to '/CFMIP/COSPv2.0/tags/v2.1.4cesm/src' path not found and the ./manage_externals/checkout_externals fails

Can you please help?

I think the issue is that older versions of CESM rely on subversion to checkout code from github.com, and github has stopped offering this interface. You need to use cesm2.1.5 (which should provide identical output to 2.1.3)

Thanks for the quick reply!
with cesm2.1.5 I now get this error:

./manage_externals/checkout_externals
Processing externals description file : Externals.cfg (PATH/CESM)
Processing externals description file : Externals_CAM.cfg (PATH/CESM/components/cam)
ERROR:root:SVN access to github.com is no longer supported

Are you sure you have a clean checkout of cesm2.1.5? The two purposes of that tag were (1) to support the new NCAR computer, and (2) stop using subversion to connect to repositories on github. If I do the following:

Code: 
$ git clone -b cesm2.1.5 https://github.com/ESCOMP/CESM.git cesm2.1.5
$ cd cesm2.1.5
$ ./manage_externals/checkout_externals -v

then manage_externals completes successfully.

It worked, thanks a lot!

(I'm still confused with branches and repos in CESM. Somehow doing
git checkout release-cesm2.1.5
Is not the same as clone from new?)

This looks like it might be an issue with manage_externals. This is from a temp directory where I already tried to checkout CESM2.1.4 but failed due to the aforementioned issue with subversion and github:

Code: 
$ git checkout release-cesm2.1.5
Previous HEAD position was 4003996 Fix release number
HEAD is now at 7a6c5b0 Update for cesm2.1.5-rc.01
$ ./manage_externals/checkout_externals -v
Processing externals description file : Externals.cfg (${temp_dir}/cesm2.1.5)
Processing externals description file : Externals_CAM.cfg (${temp_dir}/cesm2.1.5/components/cam)
ERROR:root:SVN access to github.com is no longer supported

ERROR: SVN access to github.com is no longer supported

I suspect this is what you were seeing as well, and the issue is that ${temp_dir}/cesm2.1.5/components/cam/ needed to be updated from the CESM2.1.4 tag to the CESM2.1.5 tag before Externals_CAM.cfg was processed. I'm not sure why manage_externals did not do that... but I'm glad the clean checkout worked for you!

Hi, mlevy,

git clone -b release-cesm2.2.1 GitHub - ESCOMP/CESM: The Community Earth System Model CESM2.2.1
./manage_externals/checkout_externals, but it works well 2 months ago.... i do not know what happens.
