connection failures to svn.cactuscode.org

Roland Haas created an issue

I am getting connection failures to svn.cactuscode.org using svn 1.9.7 on Debian buster (which is starting to phase out tls 1.0 and 1.1 support https://lists.debian.org/debian-devel-announce/2017/08/msg00004.html). Namely I get:

ET_Hack$ svn checkout https://svn.cactuscode.org/projects/ExternalLibraries/zlib/
svn: E170013: Unable to connect to a repository at URL 'https://svn.cactuscode.org/projects/ExternalLibraries/zlib'
svn: E120171: Error running context: An error occurred during SSL communication

and openssl shows:

ET_Hack$ openssl s_client -connect svn.cactuscode.org:443
CONNECTED(00000003)

Is there any chance of having LSU update their webserver so that it offer tls 1.2 (around since August 2008)?

Note that chances are that Ubuntu (which branches off from Debian unstable regularly) will pick up this change soon affecting the majority of our new Linux ET users.

For Debian this is a blocker since it prevents me from even downloading the code.

    Oddly enough: svn.cct.lsu.edu works fine. I would have assumed that svn.cactuscode.org and svn.cct.lsu.edu eventually point to the same server.

    $ openssl s_client -connect svn.cct.lsu.edu:443

    verify return:1

    verify return:1
    depth=0 C = US, postalCode = 70803, ST = Louisiana, L = Baton Rouge, street = 110 Thomas Boyd, O = Louisiana State University, OU = LSU A & M, CN = svn.cct.lsu.edu

    For Debian this is a blocker since it prevents me from even downloading the code.

    To be fair, Debian Buster is the development version of Debian, not the stable version (reducing priority due to that, at least for the moment). But yes, this should be upgraded. The server is still on Redhat Tikanga 5.11, which is the main reason for the age of the tls used.

    I've opened a ticket with IT support to have the machines OS upgraded. Steve is on CC for that. Also assigning to him.

    This is occurring again.

    Trying to access svn.cactuscode.org from my Debian box (buster) fails with:

    openssl s_client -connect svn.cactuscode.org:443
    CONNECTED(00000005)
    140630053196224:error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol:../ssl/statem/statem_lib.c:1907:

    and on a machine that would work with that command line, this one:

    openssl s_client -no_tls1 -connect svn.cactuscode.org:443
    

    fails. Indicating that the server only supports tls1.

    Since Frank had had this fixed more than a year ago, I wonder why this is happening again.
