I'm trying to install ROS Kinetic, and it keeps failing at various points in the catkin_make process, most notably and most frequently like so:

I ran:

source /opt/ros/kinetic/setup.bash

(sometimes I get the following)

-bash: /tmp/ line 38: unexpected EOF while looking for matching `"'
-bash: /tmp/ line 39: syntax error: unexpected end of file
-bash: [: 0: unary operator expected

and then


And here's the output:

No matter what, I seem to be having an error in the auto-generated file. Not sure how to proceed from here.

Are you building Kinetic from source?

I was not, but now I am. Same syntax error.

I thought there would be a different outcome. There was not.

If you don't have a good reason to build from source (and this goes for all packages, not just the "base ROS install"), then don't do it. Always try (hard) to use binary (ie: released) packages.

Please remove the Catkin workspace in which you were trying to build before, and make sure you've installed Kinetic using apt.

As to your problem: please tell us what you did exactly (ie: how you installed ROS). Also include the output of lsb_release -a, uname -rvmp, printf %q "$IFS" and ps -p $$ (note the double dollar sign).

I've added to the information above.

greentreefrog8 gravatar image greentreefrog8  ( 2020-01-06 10:04:55 -0600 )edit

Just for completeness, could you show the contents of /opt/ros/kinetic/setup.bash and /opt/ros/kinetic/

And based on the armv7l in the uname output you appear to be running this on an arm platform (RPi by any chance?).

That is not necessarily a problem, but would have been good to mention.

I would recommend to remove the source /opt/ros/kinetic/setup.bash line from your .bashrc for now. It's not needed (you can do it manually) and it would unbreak your setup for now.

As a test, please run this sed command (copy-paste it, it's a single command line):

sudo sed -i 's|rm -f "$_SETUP_TMP"|#rm -f "$_SETUP_TMP"|g' /opt/ros/kinetic/

This will make setup.shnot delete the temporary file it creates in the /tmp directory so we can take a look at it.

Then open a new terminal, type source /opt/ros/kinetic/setup.bash. It will probably still fail.

But now there should be a file called /tmp/ Open it with less /tmp/ (obviously replace SOME_RANDOM_CHARACTERS with whatever is there on your machine).

Copy the contents of this file and append it to your question text.

There might be a special character in your username, or home directory or something else that breaks parsing of the setup file.

Several of your environment variable contain a single double quote: LC_ALL, PATH, LC_CTYPE. Please fix those to not contain quotes. I would expect it to work after that.

Converted this to an answer as this most likely is the answer.

No, you should just modify your environment variables
