我无法安装 libgmp，因为看起来 snap-confine 和 snapd 具有循环依赖关系。我该如何处理？
Failed to execute operation: No such file or directory
dpkg: error processing package snapd (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of snap-confine:
snap-confine depends on snapd (= 2.23~14.04); however:
Package snapd is not configured yet.
dpkg: error processing package snap-confine (--configure):

Errors were …在Kubuntu 16.10 上安装padoka 的 PPA后，每当我运行时sudo apt dist-upgrade，我都会得到以下信息：
The following packages were automatically installed and are no longer required:
libomxil-bellagio-bin:i386 libomxil-bellagio0:i386 libxv1:i386 libxvmc1:i386
Use 'sudo apt autoremove' to remove them.
The following packages have been kept back:
mesa-vdpau-drivers mesa-vdpau-drivers:i386
如果我运行sudo apt autoremove删除自动安装的软件包，它们只会在下一次自动重新安装sudo apt dist-upgrade（并立即重新出现在该列表中）。
另外，我担心这两个包被保留而不是升级。它看起来像最新版本的mesa-vdpau-drivers需要libomxil-bellagio0和mesa-vdpau-drivers:i386需求libomxil-bellagio0:i386，但libomxil-bellagio0并libomxil-bellagio0:i386互相冲突。
我的包裹清单和系统完全是最新的，除了上述内容。此外，这种情况已经持续了几个星期。我该如何解决这些问题？
