Hi, all, I falsely tried to update boost to be libboost1.55-dev by using PPA as this link . This caused unexpected breakdowns. Firstly, many lines with "Removing ros-hydro-xxx, Removing ros-groovy-xxx" (My OS is with two versions of ROS) came out and couldn't be stopped by "ctril+ c". Finally, a red circle with a white line in the middle of it came up in the upper-right corner of desktop of Ubuntu. Then luckily I openned "Ubuntu Software Center" and it disappear the red circle by automatically repairing some missing packages. The reason is same to this question about boost in hydro.

However, when I want to compile some packages by catkin_make, it prompted that some fundamental packages couldn't be found such as std_msgs. So I have to repair the ros-hydro. I don't know how to do. Should I re-install hydro ros by the instruction for hydro installation from ROS tutorial with uninstallation?

I have tried to uninstall hydro ros by this link, but the terminal prompted

E: Unable to locate package ros-hydro


E: Unable to locate package hydro

Hopefully any advice is appreciated. Thanks!

You will need to remove the conflicting packages which you installed (and caused the uninstallation of the ros packages) Once those are removed/downgraded to the older versions you will be able to install hydro the standard way.
