Golden ISO migration script failed

[Nsight_Transport]

Trying to create the Golden ISO for 9k using the gisobuild.py. Ubuntu machine and have confirmed that the Before You Begin has been completed from 

https://www.cisco.com/c/en/us/td/docs/iosxr/asr9000/flex-packaging/b-flexible-packaging-configuration-guide-asr9000/b-flexible-packaging-configuration-guide-asr9000_chapter_011.html#task_5E4058C984234F40BE37C63A6E9AD745

The script runs great if the -m is left off. When trying to make it with the migration option I get the following: Ideas?

Building Migration tar...

Hi,

Can you please run the following command?

#which iso-read

example:

[root@xit-ucs-01 giso]# which iso-read
/usr/bin/iso-read
[root@xit-ucs-01 giso]#

It doesn’t exist. I have checked 3 different linux systems and searched for the command to download and can’t find it. Ubuntu 18.04, Alpine(docker), and CentOS 7.4.

Hi

Couple of things can be verified as follow: -


* PATH variable could be empty, IF empty can be set using export command as given example.

[21:36:00]-[cmohapat@xit-ucs-01:~]$ echo $PATH
/router/bin::/usr/cisco/bin:/usr/cisco/etc:~/bin:/bin:/usr/X11R6/bin:/usr/sbin:/sbin:/usr/bin:/usr/cisco/bin:.
[21:52:46]-[cmohapat@xit-ucs-01:~]$

To set the path following command can be used
export PATH=”$PATH:/router/bin::/usr/cisco/bin:/usr/cisco/etc:~/bin:/bin:/usr/X11R6/bin:/usr/sbin:/sbin:/usr/bin:/usr/cisco/bin”



* Rpm for iso-read might not be installed. IF not can be installed using yum command for centos system

Following is the steps to see if the system has rpm installed and iso-read is present in the package.

[21:32:54]-[cmohapat@xit-ucs-01:~]$ which iso-read
/bin/iso-read
[21:33:20]-[cmohapat@xit-ucs-01:~]$ uname -a

[21:33:27]-[cmohapat@xit-ucs-01:~]$ cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[21:33:40]-[cmohapat@xit-ucs-01:~]$ rpm -qa | grep libcdio

libcdio-0.92-1.el7.x86_64
libcdio-paranoia-10.2+0.90-11.el7.x86_64
[21:35:36]-[cmohapat@xit-ucs-01:~]$ rpm -ql libcdio-0.92-1.el7.x86_64 | grep iso-read

/usr/bin/iso-read
/usr/share/man/man1/iso-read.1.gz
[21:36:00]-[cmohapat@xit-ucs-01:~]$
Following is the command to install libcdio package in centos system

yum install libcdio

libcdio did the trick. Thanks

[Eddie Chami]

Could you let us know how you solved it, so others reading this can learn.. thx 

[Nsight_Transport]

Was resolved by adding the libcdio package which made the iso-read command available.

Great glad that worked.

[stefano.carboni]

In Ubuntu enviroment to fix the same issue I installed the following package:

sudo apt-get install libcdio-utils

Bye
