我有 Kubuntu 22.04。*buntu 中是否有程序、脚本等可以将文件夹中所有包含非拉丁字符的文件重命名为拉丁字符？例如，我有一个文件夹，其中包含以下名称的文件：

Andúril
Dúnedain
Éomer

我需要将它们重命名为：

Anduril
Dunedain
Eomer
command-line

我安装了 Libreoffice 24.2，它是从 libreoffice 网站上的 .deb 包安装的。我收到通知说有新版本可用，所以我下载并安装了 24.8 版本。然后我注意到，它并没有像以前每次升级时那样用 24.8 覆盖 24.2，而是分别安装它们。每当我打开文档时，它仍然使用旧版本。

然后我通过 apt 在命令行上卸载了 24.2，之后当我尝试启动 24.8 时，我无法启动任何 libreoffice 程序。当我输入：

libreoffice --writer

我收到此错误：

libreoffice 错误

我尝试从此处提供的 debs 卸载并重新安装：

https://www.libreoffice.org/donate/dl/deb-x86_64/24.8.1/en-US/LibreOffice_24.8.1_Linux_x86-64_deb.tar.gz

解压缩文件并输入：

sudo dpkg -i *.deb

但我仍然收到该错误。我该如何修复它？

我有 Ubuntu 20.04 和 kate 23.08.4。多年来，我一直使用 dolphin 通过 sftp 在 kate 中打开文件，使用类似以下内容：

sftp://user.name@server/path/to/file.txt

在海豚中。但是，当我现在尝试打开这些文件时，我刚刚开始在凯特中收到这些错误：

Unable to create KIO worker. Can not find a KIO worker for protocol "tags".
Unable to create KIO worker. Can not find a KIO worker for protocol "sftp".

我不确定发生了什么变化。也许有什么东西被卸载了？这是我当前安装的 kio 东西：

$ sudo apt list --installed | grep kio

是不是少了什么？

更新 我发现我安装了 2 个 Kate 实例，一个通过 apt 安装，一个通过 snap 安装。快照文件显然是当我尝试从海豚打开这些文件时打开的文件。我卸载了 snap 版本并重新安装了 apt 版本以确保我拥有最新版本，然后错误就消失了。

snap 版本和 sftp 是否存在已知错误，或者 snap 版本是否可能未正确配置某些内容，或者这两个版本可能以某种方式相互冲突？

我们有 postgres 9.5。我的计算机（Ubuntu 20.04）有 pgadmin4 8.2，但是当它连接到 9.5 服务器时，我收到此错误：

column "wait_event_type" does not exist Line 10: wait_event_type || ': ' || wait event AS wait_event, ^

我在网上搜索并发现 postgres 9.6 中进行了更改，导致较新版本的 pgadmin4 中出现此错误。

当我尝试降级到旧版本的 pgadmin4 时，出现此错误：

$ sudo apt-get install pgadmin4=6.21

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 pgadmin4 : Depends: pgadmin4-server (= 6.21) but 8.2 is to be installed

            Depends: pgadmin4-web (= 6.21) but 8.2 is to be installed
E: Unable to correct problems, you have held broken packages.

有什么方法可以降级 pgadmin4，或者在当前版本旁边安装旧版本吗？

我访问了 pgadmin 网站，但找不到任何有关旧版本的信息。

您对在这里做什么有什么建议吗？

更新2

我跑了

sudo apt autopurge

并得到了这个（不幸的是，它不允许我向这个问题添加更多文本，所以我不得不将其放入pastebin中）：

更新3

我终于能够使用 Synaptic 删除旧内核。由于某种原因，5.11.0-36 和 5.11.0-25 出现了问题。就像我必须先删除 36 个，然后它让我删除 25 个。但是在删除这些之后，我可以毫无错误地删除所有其他内容。

我有 Ubuntu 22.04 和 NVIDIA Corporation GA102 GeForce RTX 3080 显卡。显卡有 3 个 Displayport 输出和 1 个 HDMI。我有一个插入 HDMI 的华硕 VE278 显示器，它工作正常。HDMI 插入一根 HDMI 线从计算机连接到 KVM，另一根 HDMI 线从 KVM 连接到 ASUS VE278。

我还有一个插入了 Displayport 的 ASUS VE276。它有一条 Displayport 电缆直接从计算机连接到 VE276。

计算机启动时，两个屏幕都显示 POST、Ubuntu 加载徽标、登录屏幕等。

但是，当它最终加载到 KDE 中时，Displayport 显示器变黑并且我在屏幕上看到“DisplayPort 无信号”。

我正在使用 Nvidia 视频驱动程序：

lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3080 12GB] (rev a1)

当前发现的监视器：

xrandr --listmonitors
Monitors: 1
 0: +*HDMI-0 1920/598x1080/336+0+0  HDMI-0

更多信息：

lspci -k | grep -EA3 'VGA|3D|Display'
01:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3080 12GB] (rev a1)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device 389b
        Kernel driver in use: nvidia
        Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

为什么它会在一切都在启动时看到 DisplayPort 监视器，然后在 KDE 最终加载时却找不到它？
