Cannot install Etar calendar

[duplicator]

Hello,
I cannot install the Etar calendar anymore:

$ adb install /tmp/ws.xsoh.etar_36.apk
Performing Streamed Install adb: failed to install /tmp/ws.xsoh.etar_36.apk: Failure
[INSTALL_FAILED_CONFLICTING_PROVIDER: Scanning Failed.: Can't install because provider
name ws.xsoh.etar.provider (in package ws.xsoh.etar) is already used by foundation.e.calendar] 

Following the instructions from the corresponding gihub issue
https://github.com/Etar-Group/Etar-Calendar/issues/1438#issuecomment-1787392187

didn’t work in my case, /e/OS 1.15-s-20230913330639-stable-FP3.

What can I do?

Solved with this workaround found on e-foundation gitlab:
adb shell pm uninstall --user 0 doundation.e.calendar
adb shell pm install-existing --full doundation.e.calendar

Then no adb install ws.xsoh.etar_36.apk is needed. Etar seems to be provided by the system under another name.

Etar seems to be provided by the system under another name.

You’Re right, the system calendar is Etar (adjusted or rebranded), as you can see from the “About Calendar” dialog.
