无法构建 Yocto 可扩展 SDK
Fail to build Yocto extensible SDK
我是 Yocto 的新手，我一直在尝试使用 devtool 进行开发设置。
我已按照 Yocto Linux Kernel Development Manual, but I've made a change to Step #2, setting MACHINE = stm32mp1 since I'm targeting the STM32MP157D-DK1 的说明进行操作。但是，步骤 #5 失败，它要求您使用命令 bitbake core-image-minimal -c populate_sdk_ext 构建 SDK，并出现以下错误：

基于我在互联网上发现的类似问题，我尝试添加图层 meta-python2，并在我的 local.conf 中设置 IMAGE_INSTALL_append = " python-dev"。但是，问题仍然存在。
我正在使用 Linux Mint 20.2，它基于 Ubuntu 20.04 LTS。以下是活动图层：
