Hello @SébastienV 

If the checksum doesn’t match, I would suspect something is happening to the files as its being downloaded. Since Kaspersky is already flagging files as Virus\Malware when doing the local package I would suspect it is also to blame with the download.

Can you implement our AV exclusions and see if the issue persists?

Hi @SébastienV 

It seems your antivirus is considering this file to be malicious, potentially because it suspects an exe within a zip to be suspicious. If this is obtained via ma.commvault.com or store.commvault.com you can rest assured this is a trusted file.

I am attempting to reproduce your download issue using the latest bootstrapper from the store, in the interim you can also try downloading the complete media kit.

Hello

I tried to download from a serveur which has the commvault exclusion in place from kasperky, it is good for the virus because the files are not scan, this is a very good method for hidding a problem ^^

But i still have the problem :

Hello @SébastienV 

I would suggest that if Kaspersky is generating alerts about Commvault files, then exclusions are not in place.

Can you try downloading and generating the custom package on a machine that does not have Kaspersky installed?

Thank you,
Collin

yes this is what i do this morning

hi There

Today, trying to upgrade my Commserve from v11.26.49 to v11.28.36.

Looks like I missed something.

Sources were downloaded from updates yesterday in v11.28.32, while v11.28.36 was just released today, so I initiated a new download updates+sync cache job before my attempt to upgrade.

I’m pondering on my side at the moment if I should raise a case to support or postpone my migration attempt to tomorrow, and revert to v11.28.32 instead. Also considering to download sources in parallel (but this is always way slower, as I have to re-upload them to my CS...)

Laurent. 

All right folks.

So after a quick log checks, I thought that the new FR28 included 3rd-part python binaries, and I bet that this would require a reboot of my Commserve before the setup would be able to execute the python scripts… I had no popup or clear log stating this, though… (bad point ...)

So, after rebooting the server and doing nothing, the setup resumed and went on fine.

Now, it’s upgrading and updating..  Phewwwww. I had serious doubts on that one.

May I suggest that such ‘reboot needed’ would generate a POPUP window or at least a BIG EMPHASIZED ENTRY in the cvupdate.log ?
