OPKG :没有提供任何请求

Question

我有一个定制的Linux发行版，它是用Yocto/Poky构建的。我使用opkg作为软件来管理我在嵌入式系统上的包更新。我有数百个系统正在运行，并希望升级一个重要的软件包(my-custom-package)。在绝大多数情况下，一切都很顺利，但在4种系统中，我面临着以下错误：

root@hostname:~# opkg -v

因此，my-custom-package有几个Python依赖项，而opkg似乎无法找到它们。但是，当我对依赖项运行opkg info <pkg>时，我得到了一个结果，opkg找到了包。我在我的存储库上验证了要下载的压缩包是否在那里，一切看起来都很好。另外，我的一个有问题的嵌入式系统与在同一天安装的其他嵌入式系统运行在同一块区域(因此来自同一个映像、相同的编译、.)。我习惯于用远程的opkg更新软件包。大约6个月前，我在一个系统上遇到过一次这样的问题，但是，由于它是一个非关键包的升级，所以我忽略了这个问题。

我试过opkg clean，但没有成功。我阅读了手册页寻找一些帮助命令，但似乎没有任何效果。

编辑:另一个有趣的事情：

root@hostname:~# opkg download python3-core
Downloading https://my-repository/ipks/v2/cortexa9t2hf-neon/python3-core_3.5.6-r1.0_cortexa9t2hf-neon.ipk.
Downloaded python3-core as python3-core_3.5.6-r1.0_cortexa9t2hf-neon.ipk.

所以如果我想下载一个opkg找不到的包，它就能工作.

另外，一个简单的opkg list-upgradable返回相同类型的错误：

root@hostname:~# opkg list-upgradable

Answer 1

我在yocto系统上遇到了同样的问题

opkg install  libfreetype6  

我试过所有可能的开关--强制-重新安装开关工作了！！

opkg install  libfreetype6  --force-reinstall
