i have an error:: "Oops, some unexpected error occurs" when i try to download DB2 beta
Have you tried again since, Malek? We'll do some digging internally and see if we can find anything helpful on our end and get back to you here.
I have tried to download all platforms of Db2 beta successfully. Are you using this link https://db2-beta.mybluemix.net/dashboard to download? Also, could you help to provide your key so I can check if there is any issue with your key.
If you are on Linux Ubuntu 19.04 (disco), please install the package icedtea-netx for the Download Director to work.
