3. Update Desktops¶

The desktop app plugin is maintained by the bc_desktop project. Assuming you previously installed with Install Desktops you can update it with the following directions.

3.1. Do I need to update?¶

Latest version: v0.1.2

You can compare this to the locally installed bc_desktop with the following command:

grep '##' /var/www/ood/apps/sys/bc_desktop/CHANGELOG.md
#=> ## [Unreleased]
#=> ## [0.1.2] - YYYY-MM-DD
#=> ### Changed
#=> ...

where the version number should be given in the line after [Unreleased]. If the version numbers match then you can skip this update.

3.2. Instructions to update¶

Back up this directory. If you already performed Update Applications then you should have a back up of this already. In particular, the most important code lies in your custom configuration directory:
```
/var/www/ood/apps/sys/bc_desktop/local
```
We will be re-using the ood-apps-installer utility script that we used previously to install the apps to handle installation/updating of the Desktops app. Fetch the latest changes and check out the latest tag:
```
cd ~/ood/src/apps
scl enable git19 -- git fetch
scl enable git19 -- git checkout v1.2.0
```
Confirm that your center’s local configuration files under build/bc_desktop/local/ exist.

Rebuild the app:

scl enable rh-ruby22 nodejs010 git19 -- rake build:bc_desktop

Finally, we install the app to its system location at /var/www/ood/apps/sys/bc_desktop with:
```
sudo scl enable rh-ruby22 -- rake install:bc_desktop
```
