这种情况经常发生。每次我看到 RAM 使用峰值时，GUI 都会重新启动。如果有任何帮助，我将不胜感激。
还需要什么其他信息？
当我在 Virtualbox 中使用 Windows 10 时，我就遇到过这种情况，我已经将其设置为消耗 6GB 内存。我有 12 GB 内存和 25 GB 交换空间。

你能帮我解决这个问题吗？我无法继续前进，因为默认的 nodejs 是 10.19，它不受支持和维护。我在使用此版本时遇到问题，现在无法将其升级到当前版本。
我从 ubuntu 18.04 升级到 20.04，现在我的 mysql 不工作了。我记得在从mysql 5.7升级到mysql 8.0的过程中提到了一些注意事项；我记错了。
现在，我无法安装mysql。这就是我得到的：

有出路吗 ？
如何设置任务栏（Ubuntu 扩展坞）以仅显示在当前工作区中运行的应用程序？当前单击它会显示应用程序运行的所有不同位置。
在这里，2 个 Firefox 窗口在不同的工作区中运行，所以我不希望它们都显示在所有工作区中。
