Description of my issue

Hi
I wanted to install Wekan on my local raspi, no success.
See the very short logs in yunopaste: https://paste.yunohost.org/raw/unodoyuwuy
In the end the error is: Failed to provision sources : In resources.sources: it looks like you forgot to define url/sha256 or arm64.url/arm64.sha256

Could this be solved from my side or might there be something wrong with the package? Or is it related to the arm cpu of the Pi?

Thanks!

Upstream no longer ships prebuilts for arm64 so the architecture is incompatible, sorry :confused:

Oh pity.

Thanks!
