这些消息每 1 秒附加一次：
ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata3.00: configured for UDMA/33
我认为这可能与我让 powertop 将电源设置从以前的任何设置更改为自动有关。
如何告诉内核停止启用此链接？或者我如何告诉它永远不要让 ata3 进入睡眠状态？
刚从仿生升级到宇宙。该过程的一部分从 deb lxd 迁移到 snap lxd。升级成功，除了 lxd 包。尝试完成升级或使用 snap 命令安装 lxd snap 时出现此错误。
snap install lxd
error: cannot perform the following tasks:
- Download snap "lxd" (10756) from channel "stable" (invalid credentials)
为什么我会得到这个？什么证件？snapd 错误日志在哪里？
根据尝试的答案中的要求进行更新：
grep snap /var/log/syslog：

我在这里遵循指南：https ://alexpearce.me/2014/05/italics-in-iterm2-vim-tmux/
它适用于默认 tmux，但如果我通过 byobu 启动 tmux，则术语类型为screen-256color. 似乎~/.tmux.conf没有得到来源。
我尝试添加相同set -g default-terminal "tmux"的内容，~/.byobu/window.tmux但这阻止了 byobu 的启动。

为什么图像大小几乎翻倍？
启动映像后，Xenial 中的使用量要小得多，Wily 中为 727MB，而 Wily 中为 812MB，使用 du -sh /.
更新：别介意上面的问题。
从图像服务器下载图像后，它显示为 138.23MB。
为什么图像服务器报告 Xenial 版本的大小为 310.30MB，而实际上它约为 138.23MB？
我做了一些挖掘并提交了一个错误：https ://github.com/lxc/lxd/issues/2223
$ curl -s https://cloud-images.ubuntu.com/releases/streams/v1/index.json | jq -C . | less
并走到唯一具有“数据类型”的对象：“图像下载”。这就是 lxd 使用的。我遵循了该对象的路径值。
$ curl -s https://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:download.json | jq -C . | less
我在那个 simplestream 中寻找 xenial 和其他版本的条目的差异。

显示修复缺少的统一菜单解决方法的补丁。我想看看这个补丁做了什么，以便我可以将它应用到我的 MD 主干构建中（并且可能在上游提出拉取请求）。有没有办法可以在启动板中浏览这个差异？
我想我真的想要一种简单的方法来在包含 ubuntu monodevelop 包的任何源树中找到修订版 2.4+dfsg-3ubuntu2
更新：我发现了这个：https ://launchpad.net/ubuntu/natty/+source/monodevelop
更新：我终于找到了这个：http ://bazaar.launchpad.net/~ubuntu-branches/ubuntu/natty/monodevelop/natty/revision/53?start_revid=53
monodevelop.in 只是用来生成菜单条目。
我想要一个更通用的解决方案，比如来自 libappmenu 的动态菜单支持。
