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

    See: http://www.tug.org/texlive/upgrade.html - But you can install TL 2012 next to TL 2011 – Marco Daniel Jul 22 '12 at 11:07
  • Thanks, but won't this take too much disk space? LaTeX has already taken ~2Gbytes on my computer! – makhlaghi Jul 22 '12 at 11:18
  • @astroboy Depends on your situation. I have a 250 Gb disk in my laptop, which is in total less than a quarter full despite having MacTeX 2011, MacTeX 2012, TL2011 (Win), TL2012 (Win) and TL2011 (Ubuntu) installed :-) – Joseph Wright Jul 22 '12 at 11:20
  • You can install TL 2012 and remove the old folder 2011. That's all – Marco Daniel Jul 22 '12 at 11:20

    Thanks a lot Marco and Joseph. Actually my computer has 2 TeraBytes of space and most of it is empty but I want to be efficient. So I will remove and install the whole new thing when ever I have some free time. Thanks again. – makhlaghi Jul 22 '12 at 11:24

    @astroboy: there's efficient of computer resources and efficient of your time. back when i had 100 k_words_ disc space allocation (1969), there was no choice. with 2tbyte to play with, you can surely not worry! -- on my work desktop, with rather smaller disc, i've got three annual copies of tl. not particularly because i need them, but because it has saved thinking time! – wasteofspace Jul 22 '12 at 11:56
  • See this answer, which points to this answer on 'ask Ubuntu'. Apparently you can install TL 2012 from an official backport now. – jon Jul 26 '12 at 19:40
  • @wasteofspace: You are right, I don't disagree. I believe it is a matter of taste and personal preference. My need for the new tlmgr was not urgent so I could afford to wait for some free time to just remove the whole old version and install a new one (infact I am looking forward to reinstall my whole OS and update everything!). If it was urgent I would surely do as you have done. I like to be in control of what I install even though I am not using more than 8/10s of my desktop hard disk space now! – makhlaghi Jul 27 '12 at 01:28
  • @jon: Thank you I will have a look. But I use Scientific Linux. So I don't know how much that applies to my system. I will check it out. – makhlaghi Jul 27 '12 at 01:29
  • Right, well that sounds like a Red Hat question then. I like to stay in the Debian world. – jon Jul 27 '12 at 05:11
  • @MarcoDaniel Transform your comment into a true answer then I will delete my answer... – Paul Gaborit Jul 27 '12 at 10:45
