[tex-live] Errors messages installing/updating TL2013

[Angelo Graziosi]

Just for completeness I want to flag that often installing or updating 
TL2013 I got messages like this (sometimes, a lot):


TLDownload::get_file: response error: 500 Can't use an undefined value 
as a symb
ol reference (for ftp://ftp.tug.org/texlive/tlnet/archive/tap.doc.tar.xz)
TLUtils::download_file: persistent connection ok, but download failed: 
ftp://ftp
.tug.org/texlive/tlnet/archive/tap.doc.tar.xz
TLUtils::download_file: retrying with wget.
TLUtils::download_file: retry with wget succeeded: 
ftp://ftp.tug.org/texlive/tln
et/archive/tap.doc.tar.xz

This occurs not only using the main TL repository but also using CTAN 
mirrors. It occurs also on different systems (Cygwin, Mac OS X,...)


Ciao,
  Angelo.
