Hi, (Have transferred this post to stack exchange - many thanks). Only had E.OS 5.1 Hera a few days and have encountered 2 issues which I cannot resolve and can be best explained by the two uploaded screenshots. The 1st - this dialog appears whenever I open the app repository and only started to appear after I downloaded via terminal the repositories required for flatpak and sideloading. At the same time I installed FreeFileSync from the online flathub repository. The 2nd - I am endeavouring to install the repos necessary for the installation of Timeshift and have been following a procedure shown in an online tutorial. Despite having used the precise same syntax as the tutorial shows the response is the as shown. I would truly appreciate any assistance that any one can offer. Many thanks - Bob Deb
