I’m getting ready to ditch Windows by trying Manjaro 20.10 on my Intel machine (via USB)). The problem is, I need to share Thunderbird mail files between that system and my Raspberry Pi 4 running the ARM version. BOTH actually have Thunderbird 68.12.0, as verified from the command line. Yet the Intel version refuses to open files from ARM, saying it has an older version than the Pi system. WHAAA??? I’m using the Thunderbird from official repositories, stable versions, on both systems.
Any suggestions on how to proceed would be greatly appreciated.
