When I run
# tlmgr update --self
This is the reply I get:
tlmgr: package repository ftp://ftp.riken.go.jp/pub/tex-archive/systems/texlive/tlnet
/usr/local/texlive/2011/bin/x86_64-linux/tlmgr: The TeX Live versions supported by the repository
(2012--2012)
do not include the version of the local installation
(2011). Goodbye.
Could anyone guide me on how to update tlmgr to 2012? Do I have to uninstall and install TeX Live all over again?
Thanks in advance
Update: I use Scientific Linux
