When using Ubuntu to install ros, I encountered many times that apt-get failed to obtain resource connection, as shown below
Solution:
Method 1: Repeat the update and apt-get install commands according to the prompt command until successful
sudo apt-get update sudo apt-get upgrade --fix-missing sudo apt-get install ros-kinetic-desktop-full //Take the ros I downloaded as an example, the ros corresponding to different versions of ubuntu are different
Method Two:
in software and updates in settings
Find Download from, click on other sites
mirrors.ubuntu.com is the default source. Considering the wall, downloading files often fails, so choose a suitable domestic mirror source site
Update after selection
sudo apt-get update
re-install
sudo apt-get install ros-kinetic-desktop-full
can be installed successfully
