Hi asergio, i suspect that you tried to install the 1.12.0 versions on a 1.10 base system. Could you please show the versions of the system apps? Assuming I am correct: There has been a major change from 1.10 to 1.12 in regard to Ubuntu Core. Instead of Ubuntu Core 18, 1.12 is based on Ubuntu Core 20 - and this also applies to the non-system apps. Therefore, all apps >= 1.12 won't run out of the box on an 1.10 system (and vice versa - 1.10 apps also won't run on 1.12 systems out of the box). When you try to install an app without core18 / core20 (the core OS snap of 1.10/1.12) being installed, you will get the (kind of misleading) error message that you have attached. The only workaround for your situation I know of is to download the core20 snap (e.g. by connecting the device to the Internet). Nevertheless, this might have non-desirable effects and I do not recommend it. I strongly recommend to update to 1.12, first. Unfortunately, you will have to use the Image update mechanism, because there have been breaking changes between both versions. Please contact your spokesperson for details about the Image Update. Future updates (e.g. 1.12 - > 1.14, etc.) will be able via App Update again. your spokesperson for details about the Image Update. Best regards Michael
