如何在自定义内核的 Ubuntu 16.04 上安装 Snaps？

由于安装 snap core 时出现错误，我无法在 Ubuntu 16.04 中安装任何 Snap 软件包。我发现问题是由于在 Ubuntu 上使用自定义内核造成的。我的内核是针对 Surface Pro 修改的 4.4.0.20-36。任何 snap 命令的输出如下：

$ sudo snap install notes
error: cannot perform the following tasks:
- Mount snap "core" (3604) ([start snap-core-3604.mount] failed with 
exit status 1: Job for snap-core-3604.mount failed. See "systemctl 
status snap-core-3604.mount" and "journalctl -xe" for details.
)

systemctl status snap-core-3604.mount 的输出：

snap-core-3604.mount - Mount unit for core

这是因为（据我所知）上游 Linux 源代码不支持限制。你可以从中找到相应的补丁Ubuntu 主线内核并使用此补丁构建内核。此外，真的没有其他内核可以满足您的需求并允许您安装 snap 吗？
