Can't update VCG

[Penobscot]

I'm receiving the error "VCG Database update failed.  Unexpected Error handling VCG Update Task"

Most recent update was 2021-07-08 on 2.5.0. I updated to 2.5.1 today.

Thanks

Hi @Penobscot 

We have a permission related issue with last online update (not for fresh install or ISO based offline update.). To fix this, just set the correct permissions on /opt/vmware-shd/vmware-shd/app/vcgupdate.

Login to SHD appliance as root user 

Execute: chmod 555 /opt/vmware-shd/vmware-shd/app/vcgupdate

Post this vcgupdate should work correctly (No restart of service or VM is required)

[Penobscot]

This worked. Thank you

I am also having the same issue. Thanks for sharing this info.

Target MyBalanceNow

That worked for me also.  Thanks

The server has internet connectivity and passed the proxy test. FW log is clear, no block at the proxy while going to the vmware sites.

error message on UI: Downloading VCG database update failed - Unknown error in downloading VCG Database update

Thanks

Sorry for the delay in responding. 

I see a silent failure on download attempt. There are no indications in the log what is causing the download to silently fail. We may also have bug in not correctly propagating the error. Are there any proxy used in the environment to reach to internet. 

VCG updates are downloaded from:  https://shd-download.vmware.com/ and SHD appliance must be able to reach here.

You can check if SHD appliance is able to download the definitions by performing following test.

Login to SHD appliance as root user

Execute: curl -k https://shd-download.vmware.com/vcg/vcg-manifest.xml
You should be able to see response from the manifest on screen similar to the following

Hi ksram,
We use a proxy to reach to internet. There is no block in the firewall log while passing through the Proxy.
The output of the command you mentioned is below. Do you have any idea about this error message? Thanks for your support

# curl -k https://shd-download.vmware.com/vcg/vcg-manifest.xml
curl: (28) Failed to connect to shd-download.vmware.com port 443 after 130170 ms: Connection timed out

Kind regards,
Engin

Hi again,

we're now getting the error message below.

curl -k https://shd-download.vmware.com/vcg/vcg-manifest.xml

curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to shd-download.vmware.com:443

[enginozer77]

this error was again about connection. the problem solved with a firewall config. thanks for your help

Hi,

we're getting an error message while VCG updating again. curl output seems succesfull. application updated to version 3.5.0 succesfully.

the error message: VCG connect failed - Time out while waiting for connection to complete

[Penobscot]

Today I received the error, "Downloading VCG database update failed - Checksum error with downloaded data."

I wanted to look at the machine's logs and received a warning that the server's key does not match the cached one.

Hi @Penobscot ,

Can you please update the SHD to latest released version 3.5.1 and post that retry the VCG update operation?
If you still face the problem please share the SHD logs, which can be collected from SHD UI -> Settings -> Help & Support -> Support Bundle.
