When upgrading packages on Ubuntu using the apt-get upgrade command you may notice that some packages are not upgraded. Ubuntu will not upgrade packages that could have a major impact to service on the server such as the kernel, kernel headers, MySQL packages, and various others. The packages are held back by aptitude as a safeguard to keep people from upgrading packages that might keep the server from rebooting or that might corrupt something like a database. Below we show the error in more detail and explain the command that can be run to upgrade the packages that are being held back.

Earlier while upgrading PHP to version 5.3.5 on a CentOS server I copied over the details of the remi repository from another server I had upgraded PHP on. Once I started the transaction all looked well until Yum needed to verify the remi repo RPM GPG key which I had not installed so an error was provided and Yum stopped the PHP upgrade process. You can get around the RPM GPG key error by simply using the –nogpgcheck switch however that is not the correct way to resolve the problem. You should instead install the RPM GPG key and the below example shows how to install the RPM GPG key for the remi repo.

Today I was adding a note to a WordPress article I had written a couple of days ago and it appeared to POST without issue after I clicked the Update button in the WordPress admin.

After further review the content didn’t exist and it appeared that the article had not posted the update at all since there were zero revisions from today. Fixing the problem is easy by using the below information that describes where I located the error, the error itself, and how to resolve it by issuing a single MySQL command.
