Failed to run the workspace: "Installation 'org.eclipse.che.exec' failed, script exit code is 127"

Description

I started che chart using che-server:latest ( same for nightly ) with tls enabled and self signed certificate, initially che-server pod doesn’t come up and got error :

Caused by: java.lang.RuntimeException: Exception while retrieving OpenId configuration from endpoint: https://keycloak.shared.devlab.test.vlab.com/auth/realms/che/.well-known/openid-configuration

i managed to solve that by creating a generic secret that wrap ca.crt and add appropriate env variable CHE_SELF__SIGNED__CERT in the deployments and che-server pod started correctly, but i got antoher error while creating the workspace and it’s probably related to certs also, So what about the secret i’m using for ingress ? should che be aware of it also ? where am I going wrong ?

Diagnostics

Exec Agent binary is downloaded remotely

Certificate File /tmp/che/secret/ca.crt will be used for binaries downloading

gzip: stdin: unexpected end of file

/bin/sh: 244: /home/user/che/exec-agent/che-exec-agent: not found

tar: Child returned status 1

tar: Error is not recoverable: exiting now

Error: Failed to run the workspace: "Installation 'org.eclipse.che.exec' failed, script exit code is 127"

i investigated further and was a permission denied so always set security context to 1000 in order to start correctly workspaces Thanks for you support will close the ticket

@mmeliani New error message that I see

{"jsonrpc":"2.0","method":"installer/log","params":{"machineName":"dev-machine","runtimeId":{"workspaceId":"workspacegtpqri3p4awwtuhl","envName":"default","ownerId":"47f31d28-d997-4354-9584-0dab05f6cb59"},"time":"2019-02-19T15:13:17.712260179Z","text":"curl: (37) Couldn't open file /home/user/che/exec-agent-linux_amd64.tar.gz","installer":"org.eclipse.che.exec","stream":"STDERR"}}


curl: (37) Couldn't open file /home/user/che/exec-agent-linux_amd64.tar.gz

But it does not help us to find a cause. Actually, we don’t see an original error that happens during binaries downloading because installer script is too complicated and I missed that, in fact, there is another curl that does downloading, and that one we updated just help unarchive binaries.
