QA 问题：包的包版本倒退，这会破坏包提要 [version-going-backwards]

如何解决QA 问题：包的包版本倒退，这会破坏包提要 [version-going-backwards]

我正在尝试使用已通过 core-image-minimal 成功构建的 Yocto 3.1（从 5.x.x 到 6.x.x 的 pytest）的更新配方构建 devtool build 映像。该作品已添加到优先级为 6 的自定义图层，但我无法编译该图像，因为最后遇到以下错误

ERROR: python3-pytest-5.3.5-r0 do_packagedata: QA Issue: Package version for package python3-pytest-src went backwards which would break package Feeds (from 0:6.2.4-r0 to 0:5.3.5-r0) [version-going-backwards]

这与层优先级有关吗？我注意到提供 Meta-python 配方 (5.x.x) 的 pytest 层比我的层具有更高的优先级。如果不是，那是什么问题？

解决方法

试试：

INSANE_SKIP_append = " version-going-backwords"

或

ERROR_QA_remove = "version-going-backwards"

有两个错误：

致命的 QA 问题（因为它在 ERROR_QA 中）。

应选择可用的最高版本。 variable DEFAULT_PREFERENCE 或 variable PREFERRED_VERSION 可能会更改行为。还要检查 bitbake-layers 及其子命令 show-recipes、show-overlayed 和 show-appends 的输出。可能会有一些有用的东西。

安装后挂钩失败

见行：

ERROR: core-image-minimal-1.0-r0 do_rootfs: The postinstall intercept hook 'update_gtk_icon_cache' failed,details in /home/cladm1/var-fslc-yocto/build_fb/tmp/work/imx6ul_var_dart-fslc-linux-gnueabi/core-image-minimal/1.0-r0/temp/log.do_rootfs

问题是 postinstall 钩子失败。互联网上有一些解决方案（或解决方法？）。还要检查提到的日志文件。

编辑：我的第一个答案是错误的，version-going-backwards 被视为错误。
