unknown error: DevToolsActivePort file doesn't exist

This error usually occurs when trying to launch Google Chrome or other Chromium-based browsers. It indicates that the DevToolsActivePort file, which is used by the browser's developer tools, is missing or inaccessible.

There are several possible solutions to this issue:

1. Close all instances of the browser and try launching it again.

2. Check if any anti-virus or firewall software is blocking the browser from accessing the DevToolsActivePort file. Temporarily disabling such software may help.

3. Rename the folder of the browser's user profile directory and try launching the browser again. The user profile directory is usually located in the following directories:

- Google Chrome: %USERPROFILE%\AppData\Local\Google\Chrome\User Data
- Microsoft Edge: %USERPROFILE%\AppData\Local\Microsoft\Edge\User Data

4. Try running the browser with administrative privileges.

5. If none of the above solutions work, try reinstalling the browser.

It's important to note that this error can also be caused by malware or other system-level issues. If none of the above solutions work, it may be necessary to seek professional help.

这个错误通常是由于在Ubuntu上安装的谷歌浏览器缺少一些依赖项或配置问题导致的。你可以尝试以下解决方法：

1. 确保系统已经更新到最新版本。运行以下命令来更新系统：

   sudo apt update
   sudo apt upgrade

2. 检查是否缺少必要的依赖项。运行以下命令来安装可能缺失的依赖项：

3. 尝试重新安装谷歌浏览器。首先卸载现有的谷歌浏览器，然后重新按照之前提到的步骤安装。

   sudo apt remove google-chrome-stable
   wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
   sudo apt install ./google-chrome-stable_current_amd64.deb

4. 如果上述方法仍然无法解决问题，尝试使用另一个版本的谷歌浏览器。你可以尝试使用Beta版或开发者版来查看是否能够正常启动。

希望这些解决方法能够帮助你解决问题。如果问题仍然存在，请参考Ubuntu的官方文档或在相关社区寻求帮助。
