asmcli install is failing with dependencies error having shell script as error message

[devil47sid]

Not sure why but asmcli working with my automation script and installing the required ASM however if I try to run the same script manually I am getting below error

Please note that the same script have completed successfully as start-up script means there should not be any dependencies missing at all

Thanks for the report! Generally stuff like this is because of shell/OS incompatibilities. What OS and shell are you running on your local machine?

[devil47sid]

Thanks for your response. I am using Red Hat 8 (rhel-8-v20201216) and Bash

[devil47sid]

I also tried to run it with sh but no luck. I forget to point I am using Compute Engine to run this script, not local VM as all required permission is configured to the VM service account. I only have access to login

[zerobfd]

Hm, it seems to work for me with the same version of bash as RHEL8. Can you share more information about how you're downloading the script and the complete command you run from the CLI?

[devil47sid]

Sure! I am attaching the entire code. Please note I have tried with both bash and sh

Anything on this? is more information required?

[zerobfd]

Sorry, I was out all last week and getting caught up on things today. I'll take a look soon.

[zerobfd]

Can you try changing the #!/bin/sh to #!/bin/bash in your script and see if that works?

[devil47sid]

No luck and I am using latest version of asmcli

[devil47sid]

Any updates on this ?

[zerobfd]

Sorry about the delay, just getting back from vacation and catching up.

I happened to run into something similar over the holidays. Can you add unalias -a on line 2 of the asmcli tool? I'm not 100% sure, but it seems that some default configurations sometimes alias things like which to include flags that break assumptions that asmcli makes.

[devil47sid]

No luck! Still having same issues with asmcli

[zerobfd]

I think this might be fixed by #1111

[devil47sid]

Thanks for the update. Just for your knowledge I have tried to execute same script with Red Hat 7 instead of 8 and it worked perfectly.

I will be waiting for new update and I hope this resolves this issue otherwise we will have no option but to downgrade to Red Hat 7 for sometime.

[zerobfd]

https://storage.googleapis.com/csm-artifacts/asm/asmcli_1.12.2-asm.0-config2 should have the fix
