Error message

If you're trying to get your site to post tweets to Twitter using the Twitter module and if, in the process of authorising the application, you end up with a message asking you to go back to your site and enter a provided PIN number, then you are a bloody idiot.

Just as I was.

Today, I was trying to get Drupal to automatically announce new posts on Twitter. To do this, I had to install the Twitter and OAuth modules. Following instructions, I created an application on Twitter and linked my Drupal account to it configuring it to announce new posts upon publishing them. However, this did not work as I ran into the following long-winded error message in the logs:

When using Eclipse (Indigo) earlier today, I ran into the following error message while trying to push my commits upstream:
An internal Exception occurred during push: [URL] git-receive-pack not permitted

My upgrade from Lucid to Precise did not go well and I've been battling errors ever since. I ran into the following error when trying to reinstall the php5-gd extension for PHP:
No apport report written because MaxReports is reached already

After my upgrade from Lucid to Precise (and thereby, from MySQL 5.1 to 5.5), I found that my MySQL instance was not running. When I tried to start the service all I got back was that it had failed to start.

I checked the system log (sudo tail /var/log/syslog) to see if I could divine the cause of this issue and I found the following messages:
init: mysql post-start process (5075) terminated with status 1
mysql respawning too fast, stopped

After an upgrade from Lucid to Precise, my PHP install started complaining about a library:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/gd.so'

While I've got a hunch that the actual problem is related to issues I had during the upgrade, turning this error (and other similar ones) off is as simple as going into /etc/php5/conf.d and renaming the file, in this case gd.ini to something like gd.ini.bak.

So I tried updating one of my boxen running the Lucid Kubuntu LTS to the new Precise Pangolin beta. During the upgrade, I received an error message stating that adobe-flashplugin could not be upgraded. I ignored it and continued with the upgrade and all went swimmingly. Once the upgrade was completed and I had rebooted, when I tried to run an apt-get update, I ran into an error with respect to the adobe-flashplugin package. When I tried to remove it, it did not work. As a stop-gap measure, I removed a number of packages that depended on it including Firefox and sun-java6.

On an Ubuntu box, I tried using the locate command to find information about a package and ran into the following error:

mlocate: can not stat () `/var/lib/mlocate/mlocate.db': No such file or directory

The locate program (should) routinely builds a database of files on the box and searches it when we call it. As the error message states, this database appears to be missing thereby leading to the error. Fixing it is as simple as calling:
updatedb

which should build the database.

Hope this helps!

If you find that you Drupal installation is WSOD-dead with the following error message:
Error: Class 'SelectQueryExtender' not found in includes/pager.inc

then this means that you've messed up the Drupal (7, at the time of writing) registry somehow. You might have done this during an import/export operation where you forgot to export the registry and registry_file tables, or as I did, you have foolishly just emptied them to clear up issues with a missing class file that Drupal fastidiously continues to track.

One of my laptops which is running on Kubuntu Lucid decided to stop connecting to my network today. I found that the KDE network-manager applet (or is it a plasmoid? :S) had decided to disable itself. Clicking it stated so with no option to re-enable it (nice UI, boys). Getting to the commandline and starting the network-manager service did not help. I also found that accessing the System settings networking configuration gave me corrupt XML file errors.
