foundation.e.tasks (Tasks) conficts with org.dmfs.tasks (OpenTasks)

• /e/ version: build date 2020-04-28 android 9
• Device model: Fairphone 3
• When it started to occur: I installed /e/ yesterday (2020-04-29)
• Reproducible with the last /e/ version: yes
• Reproducible with LineageOS: I don't own a linage device

The Problem

OpenTask installation fails every time.

Installing it from adb gives the error:

adb: failed to install org.dmfs.tasks_78500.apk: Failure [INSTALL_FAILED_DUPLICATE_PERMISSION: Package org.dmfs.tasks attempting to redeclare permission org.dmfs.permission.WRITE_TASKS already owned by foundation.e.tasks]

• The device is unusable
• The bug is the source of a data loss or a big waste of time
• The bug concerns a third party app
• The bug concerns security
• The bug concerns privacy

Possible fixes

foundation.e.tasks should not declare org.dmfs.permission.WRITE_TASKS but foundation.e.tasks.WRITE_TASKS instead.
