Hi, i'm a complete noob in Libreelec, linux and Raspberry PI 3b+. I installed 9.2.1 via site installer and got all these errors. Somewhere here in General Help discussions i saw a thread with problems like mine and someone suggest to install 9.2.0 instead. I did it and just to be sure with another SD card.
And now it's same problems - cannot install any add-on, cannot connect to LibreELEC Add-ons repo (yes, i did 30 seconds waiting in network settings), update failed on all existing add-ons.
So i tried: to install some script from BANNEDREPO as suggests a lot of videos - it didn't work because "installation failed".
tried to clear cache - nothing changes.
tried to delete addon27.db file - nothing changes
tried to install custom repos with some scripts or add-ons that should fix everything according to youtube videos - same result, nothing.
tried to factory reset - same result.
Could it be that 9.2.0 and 9.2.1 just don't work with my Raspberri PI 3b+?
