I'm following space invader one's YouTube tutorial for installing immich on unraid.

I've installed the first container however keep getting the following error when trying to install the immich container:

Error: failed to register layer: rename /var/lib/docker/image/btrfs/layerdb/tmp/write-set-840664239 /var/lib/docker/image/btrfs/layerdb/sha256/e85e2124f93f802837e1ae23fe0eab1238ea3cecbc9e1650d954c5fe335e68a8: file exists

I've never had this issue when installing containers before. Is anyone able to assist? Thank you

You could try recreating the docker image to see if it helps.

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#re-creating-the-docker-image-file

Then:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#reinstalling-docker-applications

Also see below if you have any custom docker networks:

https://docs.unraid.net/unraid-os/troubleshooting/common-issues/docker-troubleshooting/#restoring-docker-custom-networks

alot has changed and is needed to use immich on unraid.

redis is gone use valkey.

I've made guides for this exact reason...

Due to the changes spaceinvaders videos are now more general overview of how to install and what to look for:

most likley dcoker errors and issues with a exisintg image on unraid, however bitnami pulled redis and the image is partail used.

per the other person forum my sugestion of deleting the docker and its image worked for them

go to advance view:

click on the bad image or old non existing images and delte them:

then delete the docker and remove it image:

make sure the box is checked:



as we need unraid to initate a new docker pull for the tempalte.

once the old images are gone. and immihc, postgres and redis are gone.

reinstall them. as unradi still has the tempate data and your server data is still on disk...

click add container:

in the drop down list:

re select the docker you deleted and apply it to intatea docxker image pull and have the docker back



as this is simlar that happened to user:

Only think I can really recommend is start any docker you want to keep and run the script here to let docker clean up the images
