How to Boot Ubuntu 22.04 into Rescue / Emergency Mode
|
||||
======
|
||||
Hello geeks, booting Ubuntu 22.04 (Jammy Jellyfish) into rescue and emergency mode helps to reset the forgotten user password, fix the file system errors and disabling or enabling systemd service during boot.
|
||||
|
||||
In this post, we will learn how to boot Ubuntu 22.04 LTS system into rescue and emergency mode. Rescue mode is similar to single user mode where are all troubleshooting steps are executed. Rescue mode loads the minimal environment and mount root file system.
|
||||
|
||||
Whereas in emergency mode, we get the single user shell without starting any system services. So emergency mode is required when we can’t boot the system into rescue mode.
|
||||
|
||||
### Boot Ubuntu 22.04 into Rescue or Single User Mode
|
||||
|
||||
Head to target system which you want to boot into rescue or single user mode. At the boot press ‘SHIFT & ESC’ key to enter into grub bootloader screen.
|
||||
|
||||
![Default-Grub-Screen-Ubuntu-22-04][1]
|
||||
|
||||
Choose the first option Ubuntu and press ‘e’ to enter edit mode.
|
||||
|
||||
Go the end of line which starts with linux and delete the string ‘$vt_handoff’ and add the string ‘systemd.unit=rescue.target’
|
||||
|
||||
![rescue-target-ubuntu-22-04][2]
|
||||
|
||||
After making the changes, either press Ctrl+x or F10 to boot in rescue mode,
|
||||
|
||||
![Troubleshooting-Commands-in-Rescue-Mode][3]
|
||||
|
||||
Once you enter into rescue mode, run all troubleshooting commands and to reboot the system run ‘systemctl reboot’ command
|
||||
|
||||
### Alternate Way to Boot System into Rescue Mode
|
||||
|
||||
Reboot the system and press ‘ESC & Shift’ Key to go to grub boot screen.
|
||||
|
||||
Choose the 2nd option ‘Advanced Options for Ubuntu’ –> Choose recovery mode option and hit enter –> Choose Root (Drop to root shell prompt).
|
||||
|
||||
Example is show below
|
||||
|
||||
![Boot-Ubuntu-22-04-Rescue-Mode][4]
|
||||
|
||||
Once you have root shell, run commands to recover and fix the system issues and finally use ‘systemctl reboot’ to reboot the system.
|
||||
|
||||
### Boot Ubuntu 22.04 into Emergency Mode
|
||||
|
||||
To boot the system into emergency mode, first go to grub screen.
|
||||
|
||||
![Default-Grub-Screen-Ubuntu-22-04][5]
|
||||
|
||||
Select the first option as ‘Ubuntu’ and press ‘e’ to edit. Look for the line which starts with linux word, go to the end of that line, remove the string $vt_handoff and add the string ‘systemd.unit=emergency.target’
|
||||
|
||||
![Emergency-Mode-Ubuntu-22-04][6]
|
||||
|
||||
Press Ctrl+x or F10 to boot the system into emergency mode,
|
||||
|
||||
![Command-in-Emergency-Mode-Ubuntu-22-04][7]
|
||||
|
||||
Similarly in rescue mode, you can perform all the troubleshooting in this mode and once done reboot the system with command ‘systemctl reboot’.
|
||||
|
||||
That’s all from this post. I found it informative and don’t hesitate to share this among your technical friends. Kindly post your queries and feedback in below comments section.

LibreOffice 7.4: Top New Features and Release Details
|
||||
======
|
||||
This post contains the top new features of LibreOffice 7.4 (upcoming) across Writer, Calc, Impress and other core modules.
|
||||
|
||||
**This post contains the top new features of LibreOffice 7.4 (upcoming) across Writer, Calc, Impress and other core modules.**
|
||||
|
||||
The LibreOffice team improves the famous free and open-source office product with each iteration. Perhaps the only stable and well-managed open-source project as a replacement to Microsoft Office.
|
||||
|
||||
The LibreOffice 7.4 version (planned in August), bringing regular updates to core modules including Calc, Writer and Impress with features and enhancements. Furthermore, in this release, the compatibility with Microsoft Office improved with changes to the core filters and platform updates.
|
||||
|
||||
Before we round up the new features, here’s a tentative schedule for LibreOffice 7.4:
|
||||
|
||||
### Schedule
|
||||
|
||||
| Milestone | Release Date |
|
||||
| :- | :- |
|
||||
| Alpha 1 | May 9, 2022 – May 15, 2022 |
|
||||
| Feature Freeze | Jun 6, 2022 – Jun 12, 2022 |
|
||||
| Beta 1 | Jun 6, 2022 – Jun 12, 2022 |
|
||||
| RC1 | Jul 4, 2022 – Jul 10, 2022 |
|
||||
| RC2 | Jul 25, 2022 – Jul 31, 2022 |
|
||||
| RC3 | Aug 8, 2022 – Aug 14, 2022 |
|
||||
| Release 7.4 | Aug 15, 2022 – Aug 21, 2022 |
|
||||
|
||||
### LibreOffice 7.4 Features
|
||||
|
||||
#### Calc
|
||||
|
||||
First and foremost, the most crucial change coming in 7.4 is the support of 16k columns in LibreOffice Calc. It was available in earlier LibreOffice 7.3 but hidden as an experimental option. Finally, it is open to support 16384 columns, i.e. up to XFD. Additional columns are going to help several high-volume data work.
|
||||
|
||||
![LibreOffice 7.4 Calc now supports 16k columns.][1]
|
||||
|
||||
Second, the Autosum button gets the following [additional functions][2] to improve productivity and save time.
|
||||
|
||||
* COUNTA
|
||||
* PRODUCT
|
||||
* STDEV
|
||||
* STDEVP
|
||||
* VAR
|
||||
* VARP
|
||||
|
||||
![Additional options in Autosum button][3]
|
||||
|
||||
Moreover, the height of the formula bar is now part of the *.ods files. Hence, you can see the height retained after saving the file and opening it. Earlier, it was being reset to the default height. It is one of the small changes but has a more significant impact on heavy Calc users.
|
||||
|
||||
![Height of Calc Formula bar][4]
|
||||
|
||||
In addition, a new menu option `Sheet > Navigate > Go to Sheet` shows an entire new dialog which is similar to the Writer’s Go to Page.
|
||||
|
||||
#### Writer
|
||||
|
||||
Firstly, the hyphenation settings get three new options. You can now specify the size of the hyphenation zone, minimum word length and ability to stop hyphenating the last word.
|
||||
|
||||

||||

|
||||
|
||||
Secondly, the menu item Tools > Update > Update now updates the preview of all OLE objects. Also, if you are importing a DOCX file in LibreOffice 7.4, the paragraph borders bring more clarity. In addition, the import also improves the Rich text and checkbox contents inside the text box for DOCX imports. Moreover, Write 7.4 now supports clearing breaks from Word files improving layout consistency.
|
||||
|
||||
Secondly, the menu item `Tools > Update > Update all` now updates the preview of all OLE objects.
|
||||
|
||||
Also, if you are importing a DOCX file in LibreOffice 7.4, the paragraph borders bring more clarity. In addition, the import also improves the Rich text and checkbox contents inside the text box for DOCX imports.
|
||||
|
||||
Moreover, Writer 7.4 now supports clearing breaks from Word files improving layout consistency.
|
||||
|
||||
#### Impress
|
||||
|
||||
The significant change in Impress is a new Theme tab in the Slide properties for the master slide. It contains several accent colour options which control all the sildes in your presentation. It will be a really neat feature in this version.
|
||||
|
||||
![New Theme option in Slide Master Properties][6]
|
||||
|
||||
### Common Updates (across all modules)
|
||||
|
||||
Firstly, the most important change as a standard feature is LibreOffice now supports WEBP images officially. You can directly export and import WebP images across Writer, Calc, Draw etc. Now you do not need additional software to convert WEBP images, especially in Linux systems.
|
||||
|
||||
Moreover, the support for Windows compressed enhanced meta file (EMZ/WMZ) also lands in this release.
|
||||
|
||||
![New WEBP Image Support][7]
|
||||
|
||||
Secondly, the Fille > Recent Documents can remember the state of the last opened document, whether it was read-only or editable.
|
||||
|
||||
The 3D shapes lighting gets some bug fixes and corrections corresponding to the ODF specifications.
|
||||
|
||||
### Performance Updates
|
||||
|
||||
A bunch of performance boosts also makes this an important release of LibreOffice. Here’s a quick recap of the performance boosts.
|
||||
|
||||
* [The Text Layout performance gets around a 60% boost][8]
|
||||
* [Calc formula re-calculation][9]
|
||||
* Improved performance of [VLOOKUP][10], COUNTIF and SUMIF
|
||||
* [And CSV file import][11]
|
||||
|
||||
That’s not all. LibreOffice 7.4 also brings a huge set of filters (export and import) for Microsoft Office 365 file types, extended PDF export options (such as a sign) via command line, updated language support and API changes.
|
||||
|
||||
### Download LibreOffice 7.4 for Testing

如何启动 Ubuntu 22.04 进入救援/紧急模式
|
||||
======
|
||||
极客们好，将 Ubuntu 22.04（Jammy Jellyfish）启动到救援和紧急模式有助于重置忘记的用户密码，修复文件系统错误以及在启动过程中禁用或启用 systemd 服务。
|
||||
|
||||
在这篇文章中，我们将学习如何启动 Ubuntu 22.04 LTS 系统进入救援和应急模式。救援模式类似于单用户模式，所有的故障排除步骤都在这里进行。救援模式加载最小的环境并挂载根文件系统。
|
||||
|
||||
而在紧急模式下，我们得到的是单用户 shell，而不启动任何系统服务。因此，当我们无法启动系统进入救援模式时，就需要紧急模式。
|
||||
|
||||
### 启动 Ubuntu 22.04 进入救援或单用户模式
|
||||
|
||||
前往你想启动到救援或单用户模式的目标系统。在启动时按下 “SHIFT+ESC” 键，进入 grub bootloader 页面。
|
||||
|
||||
![Default-Grub-Screen-Ubuntu-22-04][1]
|
||||
|
||||
选择第一个选项 Ubuntu，并按 “e” 键进入编辑模式。
|
||||
|
||||
在以 linux 开头的一行末尾，删除字符串 “$vt_handoff” 并添加字符串 “systemd.unit=rescue.target”。
|
||||
|
||||
![rescue-target-ubuntu-22-04][2]
|
||||
|
||||
做完修改后，按 Ctrl+x 或 F10 在救援模式下启动。
|
||||
|
||||
![Troubleshooting-Commands-in-Rescue-Mode][3]
|
||||
|
||||
进入救援模式后，运行所有的故障排除命令，并运行 “systemctl reboot” 命令来重启系统。
|
||||
|
||||
### 另一种启动系统进入救援模式的方法
|
||||
|
||||
重新启动系统并按下 “ESC+Shift” 键，进入 grub 启动界面。
|
||||
|
||||
选择第二个选项 “Advanced Options for Ubuntu”->选择恢复模式选项并点击回车->选择 Root（进入 root shell 提示）。
|
||||
|
||||
下面是一个例子
|
||||
|
||||
![Boot-Ubuntu-22-04-Rescue-Mode][4]
|
||||
|
||||
当你有了 root shell，运行命令来恢复和修复系统问题，最后使用 “systemctl reboot” 来重启系统。
|
||||
|
||||
### 引导 Ubuntu 22.04 进入紧急模式
|
||||
|
||||
要启动系统进入紧急模式，首先进入 grub 页面。
|
||||
|
||||
![Default-Grub-Screen-Ubuntu-22-04][5]
|
||||
|
||||
选择第一个选项 “Ubuntu” 并按 “e” 键进行编辑。寻找以 linux 开头的一行，移到该行的末尾，删除字符串 $vt_handoff 并添加字符串 “systemd.unit=emergency.target”。
|
||||
|
||||
![Emergency-Mode-Ubuntu-22-04][6]
|
||||
|
||||
按 Ctrl+x 或 F10 将系统启动到紧急模式。
|
||||
|
||||
![Command-in-Emergency-Mode-Ubuntu-22-04][7]
|
||||
|
||||
同样，在救援模式下，你可以在这个模式下执行所有的故障排除，完成后，就用 “systemctl reboot” 命令重启系统。
|
||||
