GNS3 2.0.3 Error on Ubuntu 16.04LTS: IOS/IOU_name.bin%20is%20not%20executable

GNS3 2.0.3 Error Message on Ubuntu 16.04LTS:

home/rana/GNS3/images/IOU/i86bi-linux-l2-adventerprisek9-15.6.0.9S.bin%20is%20not%20executable


Some fellows came across the above error, while adding/configuring IOS/IOU on GNS3 2.0.3 and the development version GNS3 2.1.0 running on Ubuntu 16.04LTS machines. The error message is self explanatory, and just needs you to add execution rights to the IOS/IOU files in GNS3's images directory, like below and can be repeated for all IOS/IOU giving the same error:

(The below example assumes GNS3's default directories, and shows rights inclusion to L2 IOU, L3 IOU and a c7200 router IOS, just open a terminal with Ctrl+Alt+t, and do the following from '/home/user' directory)


rana@Ubuntu16:~cd GNS3/images/IOU
rana@Ubuntu16:~/GNS3/images/IOU$ sudo chmod +x i86bi-linux-l2-adventerprisek9-15.6.0.9S.bin
[sudo] password for rana: 
rana@Ubuntu16:~/GNS3/images/IOU$ sudo chmod +x i86bi-linux-l3-adventerprisek9-15.4.1T.bin
rana@Ubuntu16:~/GNS3/images/IOU$ cd ..
rana@Ubuntu16:~cd GNS3/images$ cd IOS
rana@Ubuntu16:~/GNS3/images/IOS$ sudo chmod +x c7200-adventerprisek9-mz.153-3.XB12.bin
rana@Ubuntu16:~/GNS3/images/IOS$ 

Now, open GNS3 again and add the IOS/IOU again in Preferences Tab, everything should work as intended.


HTH,
Rana Tauqeer.
