在从头开始新安装（不是升级）的 Ubuntu 24.04 上，我在运行时收到此错误

$ sudo apt-get build-dep -y vlc  
Reading package lists... Done
E: You must put some 'deb-src' URIs in your sources.list

24.04 之前的修复是对 进行编辑/etc/apt/sources.list，但现在在 24.04 上：

$ cat /etc/apt/sources.list
# Ubuntu sources have moved to /etc/apt/sources.list.d/ubuntu.sources

这是 24.04 的新文件

$ cat /etc/apt/sources.list.d/ubuntu.sources 
Types: deb
URIs: http://us.archive.ubuntu.com/ubuntu/
Suites: noble noble-updates noble-backports noble-proposed
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg



Types: deb
URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

如何添加deb-src到新文件/etc/apt/sources.list.d/ubuntu.sources？

有谁知道如何通过名为 RDD Process 的 firefox 子进程来解决这个高 cpu 使用率...或者作为临时创可贴如何禁用“RDD Process”，直到它在 firefox 上得到修复？作为一个忠实的 ff 用户，自从“有龙”时代以来，我不想停止使用 ff，但是新的 ff 用户不会忍受这个 ff bug

这是顶部显示的

这只是前几天开始的......以前我从未见过 RDD

firefox   118.0a1 (2023-08-19) (64-bit)


uname -m && uname -r && cat /etc/*release

是的，通过发出重置我的本地设置并没有帮助

        rm -rf ~/.mozilla
        rm -rf ~/.cache/mozilla

这是在一个强大的桌面上，并且这个 RDD 进程始终使用高 CPU ......这不是一个临时短暂的 cpu 峰值......但是，在反复杀死 Firefox 并重新启动后，RDD 确实在几个这样的周期中重新出现......我写 RDD 流程已经消失了，但整个事件序列在过去一周左右的时间里又重复了一遍

与上述 RDD 问题巧合的是，YouTube 现在有时无法在单击视频时播放视频，但同一视频在 Vivaldi 等其他浏览器上可以正常播放

下面的答案不能解决这个高CPU问题...我怎样才能禁用“RDD进程”直到它得到修复？我不希望 cpu 核心整天挂着，因为我不断使用 firefox，即使只查看像 SO 这样行为良好的网站...在杀死 ff 后一切正常，直到我尝试观看 YouTube 视频，此时 cpu 达到 100%并永远保持固定并且 YouTube 视频无法渲染

更新汉堡菜单 -> 故障排除模式 -> 重新启动...只是为了禁用所有插件之后 RDD 问题消失，但是如果没有我的插件我永远不会使用 ff 所以这不是一个解决方案

如何走出这个洞？

我没有问题清除任何包来解决这个问题。这正是阻碍 Linux 大规模采用的边缘案例。我的直觉告诉我要保持低调，直到冒犯包所有者将他们的修复推到上游。

我尝试了很多猜测，包括……无济于事……建议？

在启动时它直接进入可怕的 grub 提示符

Ubuntu 20.04 运行良好（ /dev/sda5 ），直到我删除（在 gparted 中）一个未使用的分区 /dev/sda6 然后自动重命名以下分区 /dev/sda7 然后被称为 /dev/sda6 （gparted 中的错误？它应该将 7 保留为 7) ... 盒子在原来 /dev/sda7 上的 Fedora 双重启动到现在也运行良好

这是一台 2012 年的老式笔记本电脑，我在 bios 中没有看到任何提及 UEFI ...当我运行引导修复时收到以下消息

当前会话处于 BIOS 兼容模式。请在您的 UEFI 固件中禁用 BIOS 兼容/CSM/Legacy 模式，并从与 UEFI 启动模式兼容的 live-CD（或 live-USB）中使用此软件。例如，在确保您的 BIOS 设置为以 EFI 模式启动 USB 后，使用 Boot-Repair-Disk-64 位 ( www.sourceforge.net/p/boot-repair-cd ) 的 live-USB。这将启用此功能。

https://paste.ubuntu.com/p/btw3GkGGqB/ 有什么建议吗？

目前我在这个盒子上的 live usb 上启动了 gparted 显示

这发生在我上次系统更新之后......重新启动和/或另一个系统更新后相同......有什么想法吗？

什么是 snap 等价于发行

apt-file search X11/extensions/XKBrules.h # header file some repo uses who's compile fails as it cannot find this file

# ... above returns with

libxkbfile-dev: /usr/include/X11/extensions/XKBrules.h

上面让我确定哪个 Ubuntu 包libxkbfile-dev包含文件/usr/include/X11/extensions/XKBrules.h

上面的美妙之处在于它搜索所有包，而不仅仅是那些已经安装的包

如何识别哪个快照包包含给定的文件名？（即使我还没有安装那个 snap 包）

在新机器上，为了使上述 apt-file 正常工作，机器必须进行以下运行以安装所有 Ubuntu 软件包的最新索引

sudo apt install apt-file -y  && sudo apt-file update

我正在寻找与 sn​​ap 包等效的功能

... 为什么 ？一个常见的用例是：如果我正在编译其他人的代码并且缺少头文件，那么我需要知道要安装哪个包来获取缺少的头文件（假设丢失的文件实际上存在于它经常用于 Ubuntu 包的包中并且随着项目迁移到 snap 将越来越多）

docker ps永远挂起是第一个症状，所以我清除了 docker 并尝试重新安装......安装永远不会完成

dpkg -l|grep docker

注意上面安装的docker失败iF...详情请参阅dpkg -l | head -3

以前的安装没问题，直到我注意到 docker ps它永远挂起......我清除了 docker，包括删除所有

apt-get purge docker-*  -y
rm -rf /var/lib/docker
systemctl daemon-reload

这是我的恰当条目

cd  /etc/apt ; grep -r docker 

sources.list.d/docker.list:deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable

然后我在 install 上面运行，它也只是永远挂起，所以在绝望中我在下面添加到删除 cmds 列表中......没有帮助

rm /var/run/docker.pid
rm -rf /lib/systemd/system/docker.service
rm -rf /etc/docker
rm -rf /run/docker.sock
rm -rf /etc/systemd/system/docker.service.d

docker version即使以root身份也只是挂起

uname -m && uname -r && cat /etc/*release

ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04 LTS"

我即将重新格式化我的笔记本电脑并从头开始重新安装 Ubuntu 20.04 ......有什么建议吗？

显然 docker-ce purge 包逻辑留下了神秘的 docker 残留物，这会阻止后续的 docker install 正常工作

PS ...我的远程 VPS ubuntu 18.04 都可以正常运行 docker 所以不知道这是否与 Ubuntu 20.04 相关，尽管我已经看到 docker 在其他 20.04 机器上运行正常

更新

是的，当我从 5.4.0-30-generic 恢复到内核 29 时，docker 工作正常，当我再次回到内核 30 时，它以同样的方式失败……这里是内核 5.4.0-30-generic

所以问题只发生在使用内核 5.4.0-30-generic 而 5.4.0-29-generic 是可以的

docker-ce    5:19.03.8~3-0~ubuntu-bionic      amd64

更新

docker 在当前具有内核 5.8.0-32-generic 的 Ubuntu 20.04 上是可以的

什么是 /usr/lib/tracker/tracker-miner-fs ？

man tracker-miner-fs

tracker-miner-fs - Used to crawl the file system to mine data.

有没有人有关于它寄回母舰的链接？

我关闭了所有 ubuntu 桌面搜索

设置 -> 搜索 -> 关闭

那么为什么这还在运行呢？

为什么这些系统启动的高资源猪在启动时会投入其中？至少他们应该知道足够的知识，以便在启动后低调几分钟，然后再破坏系统

这是我的上衣

这是它的 ubuntu 包

apt-file search tracker-miner-fs

tracker-miner-fs

这是包装说明

apt show  -a   tracker-miner-fs


Description: metadata database, indexer and search tool - filesystem indexer
 This package contains the tracker indexer for indexing your files and folders.
 .
 Tracker is an advanced framework for first class objects with associated
 metadata and tags. It provides a one stop solution for all metadata, tags,
 shared object databases, search tools and indexing.

为什么这个系统进程使用了​​我 100% 的 CPU？

如何清除它......不是通常的方式，因为它似乎被深深嵌入并且做一个简单的包装清除会破坏我的盒子

Ubuntu 18.10 gnome 终端 3.30.1

在 gnome 终端中，当我双击下面的单词background时，它才有意义，它应该只突出显示单词background

background=true

然而它突出了background=true

其他发行版的终端允许您编辑字符集以定义单词边界

我发出这个来找到我的 UUID

sudo dconf list /org/gnome/terminal/legacy/profiles:/

这表明

:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/

查看我发布的可用属性

sudo dconf dump /org/gnome/terminal/legacy/profiles:/

输出 ：

[:b1dcc9dd-5262-4d8d-a863-c897e6d979b9]
default-size-rows=42
default-size-columns=142
use-transparent-background=true
use-theme-colors=false
use-theme-transparency=false
scrollback-unlimited=true
background-color='rgb(28,30,31)'
background-transparency-percent=3
audible-bell=false

下面用于在以前的 ubuntu 版本中定义属性word-char-exceptions

sudo dconf write /org/gnome/terminal/legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/word-char-exceptions '@ms "-#%&+,./:=?@_~"'

这里的答案都不适用于 18.10 我可以指定哪些字符在 GNOME 终端中设置双击选择边界吗？

这里的更新 是有效的

gsettings set org.gnome.Terminal.Legacy.Profile:/org/gnome/terminal/legacy/profiles:/:b1dcc9dd-5262-4d8d-a863-c897e6d979b9/ word-char-exceptions  '@ms "-,.?%&#_+@~·/"'

只需替换b1dcc9dd-5262-4d8d-a863-c897e6d979b9为您自己的 UUID 值

在任何 18.10 应用程序上，当我打开一个非常宽的窗口然后我打开同一个应用程序的新窗口时，新窗口将自动最大化其大小。如何在创建新窗口时禁用此自动最大化？如果可能的话，我希望禁用任何类型的自动最大化窗口行为

我尝试了 18.04 中建议的解决方案，但在 18.10 上无法使用：

打开终端并运行

gsettings set org.gnome.mutter edge-tiling false

您可能还需要运行

gsettings set org.gnome.shell.overrides edge-tiling false

(18.04) 意外触摸屏幕边缘之一时如何禁用窗口大小调整？
