Linux Notes: Fixing Dropbox Container: Update 2

I recently updated the way I run Dropbox in a container on CentOS 7. For a history of this process within my environment, see the following articles:

• Linux Notes: Fixing the Dropbox Container
• Containers with SELinux: Dropbox on CentOS 7

Putting Dropbox in a container is required for installations of Linux that do not use the latest version of the C libraries and other bits. It is also convenient for keeping Dropbox to itself.

The major change is the need to include more libraries than those in the original container by Jan Broer. The steps are the same as the ones I took in my article Fixing the Dropbox Container. Following are the results of those changes. I also added a Makefile to the mix. I prefer those, as I can just type “make” and not the long command to build the Docker image. As testing occurs, a rebuild may be required.

The Patch

Below is the patch you can use to adopt the latest changes needed to run a headless Dropbox on CentOS, per the Dropbox Forums. This also includes the previous patch so that no fixes are lost.

Conclusion

I use Dropbox often to transfer files, and having it available on my Linux system is a must. Once I applied this patch, Dropbox started to work again. However, if you do this, be careful. When Dropbox crashes, it fills up your Dropbox storage with core files. Without this patch, core files will abound. You will want to delete them to save your Dropbox space!
