我正在尝试使用现有的colibri层为toradex colibri imx7构建meta-ros图像。

但是当我尝试构建图像时：

bitbake core-image-ros-roscore

我收到以下错误：

Collected errors:
 * Solver encountered 1 problem(s):
 * Problem 1/1:
 *   - nothing provides python-bsddb needed by python-db-2.7.16-r1.cortexa7t2hf-neon
 * 
 * Solution 1:
 *   - do not ask to install a package providing ros-core

我正在使用的bblayer：
