Unable to find image 'gliderlabs/herokuish:latest-20.' locally

Hello,
I have changed nothing on my server but when I try building my app it shows:

-----> Cleaning up...
-----> Building upgear from gliderlabs/herokuish:latest-20.
Unable to find image 'gliderlabs/herokuish:latest-20.' locally
docker: Error response from daemon: manifest for gliderlabs/herokuish:latest-20. not found: manifest unknown: manifest unknown.

I have downloaded the image with
docker pull gliderlabs/herokuish:latest-20
but it changes nothing.

I have also tried buildpacks:set with herokuish 20 and 22 but I still have the error...
I have updated dokku to the last version.

Does anyone know how to make this problem disappear?

I have solved it by using:

dokku buildpacks:set-property --global stack gliderlabs/herokuish:latest

Are you running on a non-amd64 server?

I am running on a amd64 server
Linux my-domain5.10.0-26-cloud-amd64 #1 SMP Debian 5.10.197-1 (2023-09-29) x86_64 GNU/Linux

Oh it looks like you set the image to gliderlabs/herokuish:latest-20. previously, with a trailing period. You can see that in the log message. Swapping the stack appeared to have made it work only because you stopped using the trailing period.

Oh okey thank you :)
