Hello,

Attached is the answer to the questions ...

It seems that the problem comes from the compatibility of the programs compared to the system used (currently ubuntu 21.10.).
Before, I was using Ubuntu 21.04 and everything was fine.
With Ubuntu Kylin 21.04, ditto.

Some programs no longer appear in the list of the Ubuntu launcher such as ... Streamtunner2, FFmpeg, Snap Store, ....

It would be nice if only compatible programs appeared in the Ubuntu Software list.
Or at least report that the program is not compatible.

Thank you for your interest in my problem.

Ubuntu 21.10 is in development status and not meant for public use yet (planned release date is October 14, 2021).
Who told you that you should already upgrade to that version?
Additionally you have enabled impish-proposed which is not recommended at all, except during tests of software updates.

If you want a solid and well-tested operating system, then you should go back to Ubuntu 20.04.

Thanks for your answer...
Sorry for the problem I give you....  I just wanted to see the new version... I always do that since the bebinning withe 8.04 version... And sometime, I try to help you when I have problem... I can too, test you some parts of your system...
Still sorry...

It is fine, when you want to help developing Ubuntu by testing the development version, but you should do this only, if you are able to handle problems yourself.

Especially with external software you have to expect incompatibilities, which in some cases are corrected only around the official publication date of the new Ubuntu release.

OK, Thanks...
