Until the new version is >0.7.16 (which I would guess/hope it will be by the time Maverick Meerkat ships) then keep the old version of the file, otherwise update to the package maintainer's version. If you pick the wrong option, or experience problems, you can always use Synaptic to completely reinstall the application and then re-apply this fix if necessary.

If Ubuntu send Calibre updates will I be offered the option to keep the modified file?

]]> Comment on sudo? sudon’t! Stupid “sudoers.d” by Mark http://www.peppertop.com/blog/?p=1015&cpage=1#comment-9433 Mark Wed, 01 Sep 2010 07:43:41 +0000 http://www.peppertop.com/blog/?p=1015#comment-9433 Luckily I'm technically savvy enough to handle these sorts of problems on my own machine even without setting a root password. Yes it required a reboot from a live CD, but it was just an annoyance rather than a real issue. I just posted the article as a warning for anyone else who might have thought along similar lines to me. Generally I do use sudo su if I'm going to do some more significant admin work - but in this case I was simply caught out by the fact that just creating a file using "touch" was enough to upset sudo, which isn't documented anywhere I've seen. FWIW I did plan to use visudo to edit the file once it was created - but as I mentioned in my reply to the previous comment, nowhere does it indicate that you should also use visudo to <em>create</em> the file in the first place.

It's there for situations like these. su - would have let you fix this easily. I agree that sudo has some of the worst documentation ever. However, I don't tend to use sudo to edit any of sudo's config, I always do it as root (or use visudo) just because of situations like this. It's also a good idea, when dealing with things that can backfire badly, to simply do sudo su - and then proceed normally (as root). Just my $0.02.

I did check the sudo, sudoers and visudo man pages and found them far more confusing and opaque than most man pages - the fact that the sudoers man page <em>starts</em> with a "Quick Guide to EBNF" is a clear indication that it's not designed as a quick reference guide. FWIW nothing I've read (other than your comment) makes it at all clear that visudo can be used to <em>create</em> files in the sudoers.d folder. Even the visudo(8) man page refers to the -f option as allowing visudo to "edit (or check) the sudoers file of your choice" - no mention of creating. As a result I had assumed that I needed to create the file first, before I could pass it to visudo. I don't know if your sudoers(5) man page is different to mine, but I found no mention of <em>creating</em> the files with visudo in the "#includedir" section, only of editing them.
