全部问题(ubuntu)

我已使用和禁用ctrl++键命令。altDELsudo systemctl mask ctrl-alt-del.targetsudo systemctl daemon-reload

但即使如此，如果我连续按下ctrl+ alt+DEL键命令，系统也会重新启动。

这是 Ubuntu 的一个已知问题还是预期的行为？

PS：我仅通过 SSH 使用 cli 界面。因此基于 GUI 的答案没有帮助。

我已经从 ubuntu 22.04 升级到 24.04，但 skype repo 出现了一些问题。我卸载了 skypeforlinux，但 repo...我无法删除它。

每次更新我都会收到此错误：

Err:5 https://repo.skype.com/deb stable InRelease

我尝试像这样删除 ppa：

sudo add-apt-repository --remove https://repo.skype.com/deb stable main

但我收到此错误：

我刚刚在笔记本电脑上双启动到 24.04.1。每当我打开 ubuntu 时，我都会像往常一样连接到 wifi。但是当我的屏幕休眠或进入挂起状态时，无论是我关闭它还是它自动休眠，所有网络都会消失。

我尝试过：

• sudo systemctl restart NetworkManager

• 更改wifi.powersave为= 2

• sudo apt update && sudo apt upgrade

• 运行：sudo nano /lib/systemd/system-sleep/restart-network-manager.sh 创建脚本：#!/bin/sh case $1 in post) systemctl restart NetworkManager ;; esac 然后sudo chmod +x /lib/systemd/system-sleep/restart-network-manager.sh

• 更新的驱动程序sudo ubuntu-drivers autoinstall

• 已检查rfkill list；顺便说一下，没有被阻止

暂停后所有网络仍然消失。就像是在寻找网络，但始终找不到一样

有人有想法吗？

我有一份 IP 列表，例如

（不必担心将它们发布在这里，它们都被蜜罐捕获，作为攻击性黑客源。

现在，在 bash-shell 中，我想重新格式化此列表 - 必须用逗号和空格 (, ) 替换它们之间的空格，以便在 hosts.deny 文件中轻松使用它们。我的问题是：正常的 bash 或 sed 替换总是失败，并出现错误“替换错误”。看来我需要以某种方式转义空格/逗号。

所以我的问题是：如何用逗号/空格组合替换此列表中的所有空格？

谢谢！

根据官方文档，Archer T4u 支持 USB 3，但当我将其连接到 USB 3 端口时，它被检测为 USB 2 设备（根据 lsusb 输出）。我在运行 Fedora 40 的 Ubuntu PC 和笔记本电脑上都尝试了此操作，它们都具有较新的 USB 3.1 端口。该设备无需安装任何驱动程序即可运行。

我用谷歌搜索了所有我能想到的内容，结果只找到了这个列表：https ://wiki.ubuntu-it.org/Installazione/SHA256Sum/Hash 。

我下载的文件确实与那里的哈希值匹配，但是这个来源值得信赖吗？

有没有针对 ubuntu unity 24.04.1 Noble Numbat 的官方发布的校验和？https://ubuntuunity.org上没有。

当unbound使用配置时--enable-dnstap，无法定位protobuf-c。

尽管已经安装了 protobuf-c 库或程序，但我找不到它。

我该如何解决这个配置问题？

更新：

我从这个答案中发现库名是libprotobuf-c.so.1。

其位置是通过以下方式找到的：

$ sudo find / -name libprotobuf-c.so.1
/usr/lib/arm-linux-gnueabihf/libprotobuf-c.so.1
$

我尝试通过以下方式将此文件链接到/usr/local/lib（未绑定的默认安装库目录）

$ ln -s /usr/lib/arm-linux-gnueabihf/libprotobuf-c.so.1 

并重新运行

$ ./configure --enable-dnstap

并且仍然收到与上述相同的错误消息。

我进一步尝试：

./configure --enable-dnstap --with-protobuf-c=/usr/lib/arm-linux-gnueabihf/libprotobuf-c.so.1

并且仍然收到与上述相同的错误消息。

我尝试配置的非绑定版本是 1.22.0。

此问题不重复How do I find the package that provided a file?。原因：

1. 我已经在使用dpkg。
2. 我发现使用apt search更合适，因为它显示了与描述相关的所有其他包protobuf-c。
3. 除了 之外libprotobuf-c，unbound还使用protoc-c​​程序（由未绑定成员告知我），安装后即可使用protobuf-c-compiler（参见@steeldriver 评论）。使用 不会泄露此信息dpkg。

几天前，微软的 Intune 从 Ubuntu 笔记本电脑上消失了。我尝试重新安装它，但存在依赖性问题。jammy 是否已迁移到此库的新版本？还是我搞砸了什么？

我使用的时候ls -al $HOME/.local/share/gnome-shell/是没有问题的，但是使用的时候ls -al $HOME/.local/share/gnome-shell/extensions/会出现无法访问文本的情况ls，找了很多网站，但是都没有解决这个问题。

塔式电脑

几周前从 23.10 升级到 24.04 没有任何问题。使用过程中没有任何启动问题，直到今天上午。已设置安全自动更新并允许任何更新。

今天早上启动时，它就是无法通过 IRQ 页面。只是挂在那里。

尝试在安全模式下启动，问题相同。因此，切换到 Grub 页面上显示的唯一其他内核，然后启动。使用桌面上的终端，执行 sudo 更新。这只显示了其中一个程序 KiCad 存在未满足的依赖关系的问题。它显示“无法安装某些软件包”，但没有列表。损坏的软件包列表为空。

6.8.0-47-generic 是我现在使用的内核，因为它继续通过 IRQ 页面并到达 pswrd 页面。内核 6.8.0-48-generic 或 -48 安全模式将无法启动。

我该怎么做才能恢复？或者识别问题？

注意：我有两个硬盘驱动器，前天刚刚克隆了它们，当出现此问题时我正在使用克隆的硬盘驱动器，但后来又回到了未克隆的原始驱动器。两个驱动器都停滞在同一个 IRQ 页面上，所以这可能是硬件问题，但我不知道如何识别它。

我注意到我的前面板 USB 端口不再显示在文件中，尽管它们今天早上我尝试运行 Boot-repair 时它们还在工作……但无法正常工作。命令 lsusb 显示正常的 USB 设备。

有没有办法缩小问题范围？谢谢。

编辑：这个问题突然出现真是太奇怪了，然后当我从克隆中移回原始驱动器时，启动问题也出现了。请注意，当我使用另一个硬盘时，这些硬盘没有通电。因此，我认为这一定是硬件问题，我将驱动器移到了我的备份 PC 上，主板和硬件完全不同，但同样的事情，它只能启动到内核 -47 并在内核 -48 上冻结。除了无法正常启动之外，它在内核 -47 上运行良好。

编辑：它在 -47 上无法正常工作，因为它不允许升级。当我执行更新 && 升级时，它的行为就像要执行某项操作一样，但最终却出现了以下结果：
