这个错误显示在运行 `rosdep` 命令时出现了语法错误。具体来说，它指出在 `rosdep2/main.py` 文件的第72行中有一个语法错误，即 `DEFAULT_SOURCES_LIST_URL` 变量的定义存在问题。可能是这个变量的字符串格式不正确或者缺少某些引号等。

建议检查该变量的定义，并确保其语法正确。如果需要，可以检查该文件的其他部分，以确定是否存在其他语法错误。

Traceback (most recent call last): File "/usr/bin/ceph-deploy", line 5, in <module> from pkg_resources import load_entry_point ImportError: No module named pkg_resources

这是一个 Python 的报错信息，可能是由于缺少 setuptools 库导致的。你可以尝试使用以下命令安装 setuptools 库：

sudo yum install python-setuptools

或者使用以下命令安装 pip 工具，并使用 pip 安装 setuptools：

sudo yum install epel-release
sudo yum install python-pip
sudo pip install setuptools

安装完成后，再次运行程序看是否能够正常执行。

这个错误是由于在 `gbpdistro_support.py` 文件中的一行代码结尾出现了一个错误的命令。为了解决这个问题，你可以打开 `gbpdistro_support.py` 文件并修复该行代码的错误。你可以使用以下命令打开文件并进行修复：

sudo gedit /usr/lib/python2.7/dist-packages/rosdep2/gbpdistro_support.py

然后，找到该行代码并修复它。完成后保存文件并关闭编辑器。重新运行你的程序，应该就不会再出现这个错误了。
