ZoneMinder Forums

Sorry for starting another thread, but I couldn't reply to the announcement one at http://www.zoneminder.com/forums/viewto ... ght=debian

I just wanted to thank Peter for his hard work in doing these packages, will make us debianites' lives much easier.

Two questions; Can I install these over an existing installation?

If this goes wrong, after I apt-get --remove it, a "make install" from my original tarball should replace everything with a known working copy?

(Sorry - despite having used Debian for a long time, I've never actually replaced a critical source-built application with a .deb one)

i agree, how nice with a real .deb pack!

First, you're welcome.

As to installing over an existing installation: The main problem which springs to mind is that, assuming you didn't use something like checkinstall to create an on-the-fly debian package, the install will want to create the database. Given it already exists the install will fail, leaving the package not fully installed.

And yes, replace _everything_ if it stuffs up.


If you're not worried about losing what's currently in your db, I'd do the following.

* "make uninstall" from your build area,
* make sure the zm database is gone,
* "seek and destroy" any leftover config files,
* install the zoneminder package,

PJH

Oops, I'll say it here as well; make sure you read the installed README, as post-installation you don't get apache seeing the zoneminder pages by default; you have to do one manual "ln -s".

What if I renamed the existing ZM database in sql.

"make uninstall" the existing.

Install the new .deb and let it create a new database. Finish install.

Delete new database and copy original back into its place.

Restart sql and ZM.

Sound reasonable?

How about just:
dumping your database (I did a backup script some time back to backup config, could easily be modified to do the whole database by adding the rest of the tables).
Drop the database
install package
restore the database (Created a script for this some time back as well, no modifications would need to be done).

The both scripts are in a post somewhere under the contribs topic.

My scripts are here http://www.zoneminder.com/forums/viewtopic.php?t=5381
or Ross has done a version http://www.zoneminder.com/forums/viewtopic.php?t=6299

Heh - yes, that does sound easier. Thanks!

But this package SUCKS... it has completely broken apt and dpkg i cannot remove it I cannot reinstall it to remove it... I will do a source install any day over going through that problem again.

Here's an example..
This software is great don't get me wrong... but this debian package destroyed apt totally on my ubuntu system.

sudo dpkg --purge zoneminder
dpkg: error processing zoneminder (--purge):
Package is in a very bad inconsistent state - you should
reinstall it before attempting a removal.
Errors were encountered while processing:
zoneminder
nodesyn@nexus:~/Desktop$ sudo dpkg -r zoneminder
dpkg: error processing zoneminder (--remove):
Package is in a very bad inconsistent state - you should
reinstall it before attempting a removal.
Errors were encountered while processing:
zoneminder

This is a result of the package trying to set itself up in mysql well there is no documentation... so.. what you have to do go create the mysql database either through command line or phpmyadmin or whatever you preference may be.

You HAVE to make the user zmuser AND MAKE SURE THE PASSWORD IS "zmpass" ..... if you dont do this apt will inevitably break you won't be able to update any packages download or install any new packages until you resolve this problem.

And yet... regardless of addressing that problem itself... the package breaks at least on my system anyway. If anyone is having any problems recovering on this issue feel free to email me... nodesyn@nexusconnect.com and I will be willing to help you repair it.

A little more information here and I should be able to correct the problem. Yes, I have gone through a variant of the "apt messed up" situation below, and I thought I had removed any such situation.

Was there no more information in the above? I would have expected to see the error(s) from the uninstall scripts.

? Yes, the package tries to set up mysql. As you have to do with the source install. I can only see two possibilities there:

• • You had already installed from source[/list=]
    • You didn't have the mysql server installed and setup[/list=]
    The former is easily fixable (if it's the problem . . . from memory the mysql script already checks for that). For the latter, I can make it a dependency - it just means you have to have the server on the same system. Which may make sense from a preformance POV anyway.

    Can you supply details? What's the exact system?

    It's fairly straightforward to fix: The process is to edit /var/lib/dpkg/lib/info/zoneminder.postinst and /var/lib/dpkg/lib/info/zoneminder.postrm to have "exit 0" as the first command executed. Then the install/uninstall can complete easily enough.

by all means say the package has bugs etc, but dont attack the guy that did this. Peter thankyou for your efforts i for one appricate you.

Please keep al tone civil and be grateful for the time that we all put into this project

James

James, thanks for the support. In the above case, I forgave the tone as soon as I saw he'd been stuck in "dpkg hell" - having been caught there a couple of times while developing the packages I know how it feels. You get the splitting headache, _then_ you start banging your head against the wall/grater combo

Actually, mysql-server is a dependency. So it should have been installed. It looks like there is a problem here if that's the first install of MySQL. I'll have to think about that . . .

It seems you need to create a zmuser in mysql...
