Meson明明安装后找不到accountsservice

3

我正在尝试在 Ubuntu 上构建pantheon 基本欢迎程序，但它在构建阶段一直失败，因为它找不到accountsservice. 但是accountsservice显然已经安装了。. 我正在按照页面上给出的构建说明进行操作。

操作系统信息：

Linux newbie-VirtualBox 5.3.0-40-generic #32~18.04.1-Ubuntu SMP Mon Feb 3 14:05:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

介子构建命令行：

meson build --prefix=/usr

介子输出：

最奇怪的部分是accountsservice已经安装到其最新版本。

另外，如果我做一个locate accountsservice

到底是怎么回事？为什么当它明显存在时meson找不到？accountsservice

Ubuntu 使用什么加密模块来提供全盘加密？

我正在尝试通过在此处遵循本教程来设置具有全盘加密的 Ubuntu 。

我想知道的是 Ubuntu 使用什么加密模块来加密数据？是卢克斯吗？如果不是，它使用的加密模块与 LUKS 相比如何？

无法使用 Ubuntu 16.04 连接到 Wifi

1

我刚刚在我的HP-149tx和 Windows 上安装了 16.04。我无法从 Ubuntu 访问 Wifi。即使我将笔记本电脑靠近路由器，信号也太弱。我可以确认这是驱动程序问题，因为我可以从 Windows 完美访问我的 Wifi。

我尝试纠正此问题的方法是尝试按照此处指定的说明下载并安装 wifi 驱动程序。安装驱动程序时遇到的问题如下：

(Reading database ... 174937 files and directories currently installed.)
Preparing to unpack rtlwifi-new-dkms_0.10_all.deb ...

Consult /var/lib/dkms/rtlwifi-new/0.10/build/make.log for more information.

make.log 的内容也如下：

我可以确认我的 wifi 网卡是 Realtek RTL8723BE 设备，因为这是我的 Windows 操作系统识别它的设备，并且我已经为它安装了 Windows 等效驱动程序并且它在那里工作正常。

modinfo rtl8723be 的输出如下：

Meson明明安装后找不到accountsservice

Ubuntu 使用什么加密模块来提供全盘加密？

无法使用 Ubuntu 16.04 连接到 Wifi

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
