No match for argument: qt5-default

如果在执行 `sudo apt-get install qt5-default` 命令时出现 "No match for argument" 的错误提示，可能是因为你的 Linux 发行版没有该软件包的名称。你可以尝试使用以下命令来安装 Qt 开发环境：

对于 Ubuntu、Debian 等基于 apt 的发行版：

sudo apt-get install build-essential qt5-qmake qt5-default qtbase5-dev qtdeclarative5-dev

对于 Fedora、CentOS 等基于 yum 的发行版：

sudo yum install gcc-c++ qt5-qmake qt5-qtbase-devel qt5-qtdeclarative-devel

对于 Arch Linux 等基于 Pacman 的发行版：

sudo pacman -S qt5-base qt5-declarative qt5-tools

安装完成后，你可以按照上面的步骤安装 qmake。

No match for argument: mysql-community-server

As an AI language model, I cannot determine the exact context of your query. However, if you are encountering the "No match for argument: mysql-community-server" error message while trying to install the MySQL server on your system, it could be due to the following reasons:

1. The MySQL repository is not configured on your system. To install MySQL, you need to configure the MySQL repository first. You can do this by following the instructions provided on the MySQL website.

2. The MySQL package is not available in the configured repository. In this case, you may need to update your repository or check if the package is available in a different repository.

3. The package name is misspelled or incorrect. Ensure that you have typed the correct package name while trying to install the MySQL server.

Overall, it is essential to ensure that you have followed the correct instructions for installing MySQL on your system to avoid such errors.

No match for argument: pkg-repo-manager

I apologize for the confusion. It seems that the `pkg-repo-manager` package is not available in the official repositories of OpenEuler. If you are looking for a package repository management tool specifically for OpenEuler, you may need to explore other options or use the default package management system provided by OpenEuler.

OpenEuler uses `dnf` as the default package manager, similar to Fedora and CentOS. You can use `dnf` to manage repositories and install packages. Here are some commonly used commands:

- To add a repository:

  sudo dnf config-manager --add-repo <repo-url>

- To remove a repository:

  sudo dnf config-manager --remove <repo-id>

- To install a package:

  sudo dnf install <package-name>

- To update packages:

  sudo dnf update

Please note that the availability of packages and repositories may vary depending on the specific version and configuration of OpenEuler. It's recommended to refer to the official documentation or community resources for more information on managing packages and repositories in OpenEuler.
