在对 Ubuntu 22 进行例行更新后，我现在拥有多个版本的 LibreOffice（7.3.7.2 和 7.5.1.2）。

是否可以将两者合并（以保留我放置在 7.3 中但不存在于较新版本 7.5 中的插件）？还是直接将 7.3 升级到 7.5 而无需重复？

这是由于 deb/snap 通信缺陷造成的吗？

谢谢

我有 Ubuntu 22.04 LTS 并在这篇文章之后安装了 Atom 。从图标启动后，窗口打开但保持空白，然后在几秒钟内崩溃。在终端上我得到：

$ atom

我刚刚安装了 ubuntu 22.04。我可以安装 R sudo apt -y install r-base gdebi-core：

$ R

R version 4.1.2 (2021-11-01) -- "Bird Hippie"
Copyright (C) 2021 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)

但是当我尝试从下载的文件中安装 Rstudio 时，我得到：

$ sudo gdebi rstudio-2022.02.1-461-amd64.deb 
[sudo] password for gigiux:

Dependency is not satisfiable: libssl1.0.0|libssl1.0.2|libssl1.1

一个流行的 deb 文件缺少一个基本库是很奇怪的，另外：

$ sudo apt install libssl1.1

在 Ubuntu 22.04 上安装 R 和 R studio 的正确程序是什么？

为了保证 PC 的安全，我从 Ubuntu 软件安装了防火墙配置：

在此处输入图像描述

安装一结束，我就失去了 WiFi 连接（顺便说一句，甚至 Rstudio 也无法连接到 R）。我删除了它，sudo apt-get remove firewall-config但 WiFi 仍然死了。

如何重新建立wifi？我需要在 ubuntu 中安装防火墙吗？和防病毒软件？（如果是，clamAV 可以吗？）

谢谢

我设置了 15' 不活动后的省电模式。问题是我回来后需要再次登录（例如通过移动鼠标）。有什么方法可以避免登录？

谢谢

我刚买了一个 ARDUINO MICRO，它看起来被系统识别了，因为它显示在/dev/ttyS0. 我写的草图编译没有错误，但是当我尝试上传时，我得到： 在此处输入图像描述 如果我按照建议按下重置按钮，在开始加载过程后，我得到

Global variables use 149 bytes (5%) of dynamic memory, leaving 2411 bytes for local variables. Maximum is 2560 bytes.
An error occurred while uploading the sketch
avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied

使用详细输出，我得到：

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

它看起来更像是系统错误而不是电路板的问题。会有什么问题？故障排除列表没有针对此问题提供适当的解决方案，因为它没有提及拒绝访问端口...

谢谢
