我正在 Ubuntu 上安装 SonarQube Community Build。我已将 Java 从 .tar.gz 安装到 /opt/java。我已将JAVA_HOME=/opt/java/和添加SONAR_JAVA_PATH=/opt/java/bin/java到我的 .profile 文件中。echo $JAVA_HOME并echo $SONAR_JAVA_PATH给了我预期的结果。

我已将 SonarQube 安装到 /opt/sonarqube，并且可以使用 启动它/opt/sonarqube/bin/linux-x86-x64/sonar.sh start。

仍然不起作用的是将其安装为 systemd 服务。日志显示

Java not found. Please make sure that the environmental variable SONAR_JAVA_PATH points to a Java executable

这是单元文件：

我遗漏了什么？谢谢。

当我在工作区 1 + k 上打开基于 Chromium 的浏览器 Brave 时，它​​会在所有工作区 {1, ... , k} 上打开，关闭时也是一样。

这种情况始终存在，并且只在 Brave 中发生（与 Firefox 相反）。我希望它表现得像一个普通窗口：仅在当前工作区中打开/关闭。

感觉与这个线程相关，但是它并没有解决问题。

笔记：

Ubuntu 24.04.2 
Wayland
Brave Version 1.76.82 Chromium: 134.0.6998.178 (Official Build) (64-bit)
GNOME Shell 46.0

我被带到了这家公司。我的目标之一是升级现有的自助服务终端。这个自助服务终端是他们在美国各地的客户站点上保留的 100 多个生产自助服务终端中的测试自助服务终端。我必须将其从 Ubuntu 22.04 升级到 Ubuntu 24.04。

该信息亭不具备 wifi 功能，最近已转移到仅有 wifi 接入的设施。

我使用了一台旧电脑，并在其上安装了 Windows 11，并配备了 wifi 适配器和有线以太网控制器。这个想法是使用 Windows 11 电脑作为网络之间的桥梁。因此，我将信息亭的以太网电缆插入桥上的以太网端口并将其连接到 wifi，然后在网络连接设置中建立了一座桥梁。

我安装了一个我找到的 DHCP 服务器，让它分配一个地址 192,168.42.42。我将以太网卡的地址设置为 192.168.1.1。我将客户端计算机的网关设置为 192.168.1.1。

我的 wifi 适配器设置为 dhcp。我查看了它的以太网设置，并使用此处的默认网关作为我的以太网适配器的默认网关。我对 DNS 做了同样的操作，并将 DHCP 客户端的 DNS 指向同一个位置。这一切对我来说似乎都很好。

现在我使用 Ubuntu 24.04 安装盘启动信息亭并尝试访问 google.com。没有成功。它说找不到服务器。

现在我不知道该怎么办了。

1.) 有人有更好的主意吗？ 2.) 知道我做错了什么吗？

不确定这是因为这里情况更好还是服务器故障，目前暂时尝试这里。

我有一台用作个人服务器的机器，其规格如下：

  • 2 个 Xeon E5-2690 v3
  • 华硕 Z10PA-D8 系列主板
  • Nvidia Quadro P4000
  • 1x 三星 SSD 870 EVO 500GB（系统驱动器）
  • 3x WDC WD40EFAX-68JH4N1（在 mdadm RAID5 配置中）
  • 1000W 黄金酷冷至尊电源
  • 运行 Ubuntu 24.04 LTS

它似乎有些间歇性，但我经常发现我的 dmesg 日志在多个驱动器上充斥着相同类型的 FDPMA READ QUEUED 错误。

我尝试过的：

  • 为每个驱动器购买了新的 SATA 电缆，替换了旧的
  • 重新安装连接到每个驱动器的电源线
  • 重新排列主板上使用的端口
  • 检查 BIOS 版本（是否为最新版本）
  • 检查 SMART 健康 (参见 pastebins)

系统似乎仍可用，但我不认为这些错误是好事。不过我不太确定下一步该如何诊断。驱动器 SMART 报告似乎表明它们都处于良好状态，并且 SATA 电缆都是全新的。

dmesg日志，截断（在我重新启动之前从我的终端回滚复制，下次出现错误时我将使用完整版本更新）：https://pastebin.com/j0Jnhkgt

当我在文本框中编辑文本时，我按下该backspace键，而不是将光标移回并删除一个字符，它就像我点击了浏览器顶部的上一个箭头一样。Brave 和 Edge 中都会发生这种情况。如果我按住该shift键，我会得到正常的backspace按键行为，但速度会更慢。

这刚刚开始发生。我重启后仍然出现这种情况。我使用的是 Ubuntu 22.04。

是什么原因造成的？请注意，这涉及编辑文本，例如输入搜索词时。当我点击时，backspace它会带我回到另一个网页，就像我点击了浏览器顶部的上一个箭头一样。

发生这种情况：

勇敢的：

  • 版本 1.73.105 Chromium：131.0.6778.265
  • 版本 1.75.181 Chromium：133.0.6943.141

边缘：

  • 版本 131.0.2903.112
  • 版本 133.0.3065.92

我有几个虚拟机是用 VirtualBox 使用的（现在我在 Ubuntu 24.10 下运行 v7.0）。其中有些几个月前运行过的虚拟机现在都不能运行了。实际上，我无法将它们添加到 VirtualBox 中，它拒绝打开它们并出现以下错误：

NS_ERROR_INVALID_ARG (0X80070057)

经过搜索，似乎这是一个相当通用的错误代码，并没有说明根本原因。我确信文件没有损坏：不同的 SSD 和我也有备份，但行为是一样的。

此外，我检查了虚拟机和主机的日志（在~/.config/VirtualBox），但当发生此错误时，它们没有更新。

我现在陷入困境，我必须运行这些机器，但我甚至无法添加它们来更改设置。由于没有可用的日志，而且错误很普遍，我该怎么做才能调试这个问题？

如果这很重要，那么所有表现出此行为的虚拟机都将 Windows 10 作为客户操作系统

根据评论中的提示，我创建了一个新的 VBox，并添加了相同的视频。现在它拒绝运行，说缺少操作系统。 在这里我上传了日志文件。

我有一个关于 Ubuntu 全盘加密的简单问题。

我想在我的笔记本电脑上安装带有全盘加密的 Ubuntu 24.04，但我还需要用 C 语言做一个面向操作系统的项目，用于我在大学里要上的课程。

我想知道全盘加密是否会对使用 C 的内置函数进行文件 I/O 造成一些问题？

如果这是一个愚蠢的问题，我很抱歉，但我不确定我是否已经很好地理解了 LUKS 的工作原理，以及加密/解密是在哪个级别完成的。

我的 Raspberry Pi 5 SBC 上的 PXE 启动已完成 99% 的工作 - 除了apt-get update正常工作之外，其他一切都正常。我的环境是 TrueNAS Scale 上的 TFTP 服务器，有 2 个 NFS 共享，一个用于 tftpboot，一个用于根文件系统。DHCP 设置 66 可以毫无问题地分发 TFTP IP 地址。

新的额外信息：我发现这不仅仅是 Raspberry Pi OS 的问题。如果我使用 DietPi（同样基于 Debian），也会发生同样的事情：

Err:15 https://dietpi.com/apt bookworm InRelease
  At least one invalid signature was encountered.

获取根文件系统文件的过程是：

  • 从新 SD 卡启动 pi5
  • 完成初始安装
  • 将 /boot/firmware 和 / rsync 到上面的共享（这其中不涉及 ISO 文件，就像一些 PXE 解决方案使用的一样）。rsync 已运行，--perms并且我已验证目标上的权限与源上的权限相同。

但是，当 pi5 从 PXE 启动时，apt-get update无法运行并抛出以下错误：

这表明这不是文件系统权限问题，否则无法安装新软件包。重新启动后，nginx 仍然存在并且运行良好，因此文件系统持久性也正常工作。

注意我可以按照官方安装说明添加新的 repos，例如 Docker repo。

这不是 Docker 的问题，正如许多其他搜索结果所暗示的那样；除了上述测试之外，Docker repo 从未安装在该系统上。有足够的磁盘空间可用，所以也不是这个问题。

是什么原因造成的？临时使用一个空的 apt sources.list，并sources.list.d允许 apt 运行而不会抛出错误，正如预期的那样。添加新的 repo 并运行后sudo apt-get update一切正常，所以它肯定与 SD 卡安装中的现有 repo 有关。恢复上述复制的文件会直接导致错误再次出现。

我搜索了很多，发现了几个相同的错误，但它们的解决方案在这里不起作用，例如
