for the line numbers just use vim and do a
:%s/\d\d\.//g and :%s/\d\.//g

:%s/\d{1,2}\.//g wasn’t working, apparently vim doesn’t recognize this construct. anyway the one mentioned above will work.

Hi, Thank you for your nice tips.

I have one problem.
sudo aptitude safe-upgrade
then, it goes and does 306 all packages upgrade to intrepid…
Can I no-upgrade it to intrepid without only ruby?

Looks like it only installs p72. Vulnerabilities are fixed in p174. Sorry for the downer. Instructions to install from source?

This guide is great, thanks!

I had to use sudo apt-get update and sudo apt-get install ruby guessnet instead of the aptitude commands. Not sure why as I usually use aptitude.

Nice one. Ciao!

Thanks, it worked exactly what you have specified. If possible remove the line numbers.

Ya, not to bite the hand that feeds, I really appreciate this, but those line numbers are KILLING me.

This is very helpful but I’m sure it would save people tons of time if you took out the line numbering from your code boxes. Copying and pasting takes forever this way

No, ruby 1.8.6 will be automatically uninstalled. Both belong to the ruby1.8 package. So there can only be one.

Do I need to uninstall ruby 1.8.6

When using the preference file, apt told me 1.8.6 was already the newest version for some reason. I was able to install 1.8.7 by removing preference and explicitly running:

sudo apt-get install ruby ruby1.8 libruby libruby1.8 rdoc rdoc1.8 ri ri1.8 irb irb1.8 libopenssl-ruby libreadline-ruby libreadline-ruby1.8 ruby-dev ruby1.8-dev

Then I moved the intrepid source so apt doesn’t want to upgrade 500 packages all the time.

Thanks Kares! Updated the post: removed the typos and removed the comment.

I think the error was caused by the content of the /etc/apt/preferences file, I had to remove the following lines :

5. /*All ruby*/
66. /*End ruby*/

I don’t now why synaptic did not ignore the comments.

Most importantly is there a typo at line 21 ?!

21. rdoc1.8 ri1.8

Sorry, made a mistake…

The file has to be: /etc/apt/sources.list.d/intrepid.list instead of:
/etc/apt/sources.list.d/intrepid

So rename intrepid to intrepid.list and all will be fine. I’ve updated the blogpost too.

tried it, but it doesn’t work.
aptitude update doesn’t seem to be picking up intrepid repos, and
aptitude install ruby gives these errors:
sudo aptitude install ruby
Reading package lists… Done
E: Invalid record in the preferences file, no Package header
E: Invalid record in the preferences file, no Package header

any ideas?
