#319798 - 26/02/2009 12:20 "Repair" Debian installation
Roger carpal tunnel Registered: 18/01/2000 Posts: 5683 Loc: London, UK	If you've been following my other posts, you'll know that I hosed my VPS, and that the restore didn't go too well. What I'd like to do now is repair it. By that I mean: is there a command-line that I can run that takes a look at the currently-installed packages and reapplies the binaries? It's Debian 'etch', by the way. I've got a recent, but suspect, local backup, and a less-recent, but less-supect, local backup so I'm not too bothered about my data. _________________________ -- roger

As an aside, I came up with the following: Code: dpkg --get-selections \| grep \\binstall\\b \| cut -f1 \| xargs aptitude reinstall _________________________ -- roger

Code:

aptitude reinstall -f `dpkg-query -W -f '${Package}\n'`
E: I wasn't able to locate a file for the <whatever> package. This might mean you need to manually fix this package.
 (due to missing arch)
<a few more of those>
E: Couldn't lock list directory..are you root?

Yes, I bloody well am.

Spoke too soon -- apt-get can't reinstall more than one thing at a time -- it thinks there are dependency cycles. Turning the output from the dpkg-get command into a shell script seems to be working. _________________________ -- roger

Roger carpal tunnel Registered: 18/01/2000 Posts: 5683 Loc: London, UK	Originally Posted By: Roger Turning the output from the dpkg-get command into a shell script seems to be working. Seems to have worked. Everything is now (allegedly) reinstalled. I should therefore be able to trust my binaries. I've restored the MySQL database for my CMS (drupal). I'll do the Gallery2 ones in a moment. I'll verify my qmail (and other) installation by checking hashes against an older backup. What's not good is that the following... Code: find . -type f -exec file {} \; \| grep RFC\ 822 ...is returning a list of files that shouldn't be emails, such as the avatars on my website. What a mess. _________________________ -- roger
