Way too much stuff to trust it to keep working while you perform open heart surgery on your system.Īll that said, the following Debian article explains how to cross-grade your system: The reinstallation was performed entirely from console (aptitude FTW, of course), because the console pretty much only requires a working bash (and working curses for aptitude, but if you try to do this, curses will be plentiful, you can bet on it), whereas X requires. Needless to say, this is not a good idea, when a sizable portion of the apt system (an lots of other things, really) depends on a working PERL. Then merrily proceed to try removing 1234 other packages before getting 'round to actually reinstalling PERL. This was after I manually installed a bunch of packages, including the correct version of PERL, to fix an apt screwup: you see, apt-get -f install (which is required to get a mostly-working 64-bits system) will uninstall PER元2 in order to install PERL64. Including manually fixing 600+ broken packages in aptitude, because the automatic resolver started looping, apparently due to PERL:i386 (required by installed packages) being incompatible with PERL:amd64 (required by the packages you are trying to install). Upgrading from 32 to 64 bits without explodifying my system took me the better part of a week. That said, the words "can" and "should" look nothing alike, and that is also true of an upgrade and a fresh installation.
It is, in fact, possible to upgrade Ubuntu from 32 to 64 bits. I shall cast raise dead, because this thread is one of the top results for "upgrade ubuntu to 64 bits", and the chosen answer, while admittedly the smart choice, is not the full story.
