[Bug 1931863] [NEW] Upgrade from 18.04 LTS to 20.04.2 LTS impossible

[LELIEVRE GUILLAUME]

Public bug reported:

Hi to all!
I still can't upgrade 'naturally' from  Ubuntu 18.04 to 20.04.2 due to a ppa apparently not coming from Ubuntu. The error message advised me to launch ppa purge, what I did, but nothing changed. So I started to check out a explanation and solution on forums, but found nothing usefull to my problem so far. For your information, I'm not an advanced user of ubuntu, i'm pretty much a newbie, but want to learn each time an issue occur, and I'm french, so pardon me my accent ;)

Could you please help? Thank you in advance
Guillaume
