  • Hi - the above message is a warning, not an error - it shouldn't stop packages from installing. I trake it from your message that steam itself launches, but games don't then launch from within steam? If so, what are the symptoms? The screen blanks for a while and eventually the steam UI returns having failed to launch the game? Something else? Is it any particular game, or all games? Which version of Ubuntu are you running and do you have any PPAs enabled?

  • Fall.2017, still not fixed?

    Signature by key 09D6EF97BFB38E916EF060E756A3DEF863961D39 uses weak digest algorithm (SHA1)

    every times "apt-get update" show this message.

    no SHA256 key available?

  • Hi - it's not the key that changes, but the digest used in creating signatures. Having said that: Old packages won't be re-signed, but all recent releases of the update tool and related packages should be signed with a more secure hash.

  • Hi Vivek,

    first of all thanks for helping out on this forum. Now, to get on the point, I get the warning related to weak digest algorithm. I'm using Linux Mint 18.2 which is based on Ubuntu 16.04 LTS. I know it's "only" a warning which doesn't break anything but some of the GUI applications for managing software such as Linux Mints "Update Manager" can't work as intended. For instance, every time I update my software through Update Manager I have one additional popup and click because of the warning foor weak algorithm; also, tray icon can't work properly because it has a warning. Even if I didn't use GUI apps for that it would be nice to not have unnecessary warning messages. 

    As you already know Ubuntu 16.04 is LTS release and a lot of people only use LTS versions because of system stability and (usually) better software support. Also, a lot of other distributions such as Linux Mint are based only on LTS releseas. Now, everything mentioned is a small inconvenience but it's inconvenience caused by Intels policy on (non)support for "older" operating systems. I think it's very unreasonable to drop support in any way for active LTS version and Linux users and your customers shouldn't settle with inconveniences caused by companies policies. Can you please consider this and reform your policy on updating your software that a lot of your customers depend on? 

    Thank you very much!

  • Pleas try latest key, that was generated using a 512 algorithm

  • Please remember that some files are signed with different key because of the window time, we include 512 gpg key after we got your messages but never overwrote the old ones.
