rosdep init can't find the solution to the command
problem
I used a virtual machine before, but I finally installed the dual system win10+ubuntu18.04 today. Everything went well. Then I installed ROS. I encountered a few problems. After searching, I wrote the series of solutions and sources here.
Execute after installation
sudo rosdep init
Error:
sudo: rosdep：找不到命令
Solution
Refer to https://blog.csdn.net/qq_14977553/article/details/107493616
because the package python-rosdep is missing, just install it.
sudo apt-get install python-rosdep
After the installation is complete, execute again
sudo rosdep init
Continue to report errors:
ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.
Refer to https://community.bwbot.org/topic/811/rosdep-init- or rosdep-update- the solution to the connection error. The
reason may be that the website is blocked. Modify the host file and add the ip of the website.
Open the host file:
sudo gedit /etc/hosts
Add at the end of the text:
151.101.84.133 raw.githubusercontent.com
Save and exit, re-execute
sudo rosdep init
rosdep update
The result is normal and the problem is solved.
