Synaptic Packagers Error - uses weak algorithm

[Şerban S.]

Newby to LinuxLite, trying to reload and update synaptic packages but getting the following messages.

W: https://ppa.launchpadcontent.net/mozilla.../InRelease: Signature by key 0AB215679C571D1C8325275B9BDB3D89CE49EC21 uses weak algorithm (rsa1024)

Any help and suggestions would be appreciated. Note, that I am 74 years old and still use fingers and toes to count, so please reply accordingly.

Hi!

It is a known issue. There are more posts on that.
Since the graphic update breaks due to that, use the CLI update and it will work:

Code:

sudo apt update

In order to do that, press simultaneously Ctrl + Alt + T. This launches the Terminal window.
After that, copy the code above, then paste it into the Terminal window, then press "Enter".
You will be asked for the password you login with. Enter the password then hit Enter again.
The update will start.
Whan asked if you want to proceed with the update, hit "y" and the update will go on.

I updated everything this way, including the Mozillas (Thunderbird and FireFox).
As for the warning itself, just ignore those for now. Nobody here can do anything. It is up to the PPA server administrators (Mozilla or whatever).
