ERROR: Could not determine editor to use.

这个错误通常是由于你没有设置默认的编辑器所导致的。你可以通过设置环境变量来解决这个问题。如果你使用的是 Linux 或 macOS，可以在命令行中输入以下命令：

export EDITOR=[your preferred editor]

其中 `[your preferred editor]` 是你喜欢的编辑器，例如 `nano` 或 `vim`。如果你使用的是 Windows，可以按照以下步骤设置：

1. 打开“控制面板”。
2. 选择“系统和安全”。
3. 选择“系统”。
4. 在左侧菜单中选择“高级系统设置”。
5. 在“高级”选项卡下，单击“环境变量”按钮。
6. 在“用户变量”区域中，单击“新建”。
7. 在“变量名”字段中输入“EDITOR”，在“变量值”字段中输入你喜欢的编辑器的路径。
8. 单击“确定”按钮，保存设置。

设置完成后，你应该能够使用编辑器打开你想要编辑的文件了。

Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade.

If you encounter the error message "Could not determine the upgrade" while trying to upgrade Ubuntu from 18.04 to 22.04, there could be a few potential reasons for this issue. Here are some possible solutions:

1. Make sure your current Ubuntu 18.04 installation is up to date. Run the following commands to update your system:

   sudo apt update
   sudo apt upgrade

2. Check if you have any third-party repositories or PPAs enabled. Disable or remove them temporarily, as they may cause conflicts during the upgrade process. You can use the "Software & Updates" application or manually edit the `/etc/apt/sources.list` file to disable them.

3. Ensure that you have enough free disk space on your system. The upgrade process requires additional space for downloading and installing packages. You can check the available disk space by running the command:

   df -h

4. Try running the upgrade command with the "--check-dist-upgrade-only" option, which performs a dry-run of the upgrade and checks for any issues without actually initiating the upgrade process. Run the following command:

   sudo do-release-upgrade --check-dist-upgrade-only

5. If none of the above solutions work, you can try manually editing the release-upgrades configuration file. Open the file `/etc/update-manager/release-upgrades` with a text editor, and change the value of "Prompt" from "lts" to "normal". Save the file and then run the upgrade command again:

   sudo do-release-upgrade

If you still encounter issues, please provide any error messages or logs that you receive during the upgrade process for further assistance.
