[texhax] TexLive 2015 — tlmgr update --self returns Unknown directive — travis-ci?

[Brian Dunn]

TexLive 2015, Debian "Wheezy" Linux:

As root:
tlmgr update --self

yields the following error:
Unknown directive ...containerchecksum [long number] ... , please fix it! at 
/usr/local/texlive/2015/tlpkg/TeXLive/TLPOBJ.pm line 210, <$retfh> line 5579.

Various web searches indicate a connection to something called travis-cl.

There appears to be nothing at all related to "travis" on my machine, 
searching via locate, apt-cache search, or texdoc.

It seems that this came up once TexLive 2016 was released.

How long until the 2016 DVDs arrive in the mail?

Any ideas on how to fix this in the meantime?
