Cosign: /usr/bin/cosign: cannot execute: required file not found

[Gennady-tech]

I am building kaniko two docker files

time /kaniko/executor \
--context "${CI_PROJECT_DIR}" \
${DOCKER_BUILD_ARGS} \
--dockerfile "${CI_PROJECT_DIR}/Dockerfile-swarm" \
--destination "${IMAGE_UNSTABLE_TAG_VERSION}" \
--destination "${IMAGE_UNSTABLE_TAG_HASH}"
echo "${COSIGN_PK} ${IMAGE_UNSTABLE_TAG_VERSION}"
cosign sign --key ${COSIGN_PK} ${IMAGE_UNSTABLE_TAG_VERSION}
time /kaniko/executor \
--context "${CI_PROJECT_DIR}" \
${DOCKER_BUILD_ARGS} \
--dockerfile "${CI_PROJECT_DIR}/Dockerfile-k8s" \
--destination "${IMAGE_UNSTABLE_K8S_TAG_VERSION}" \
--destination "${IMAGE_UNSTABLE_K8S_TAG_HASH}"

when signing an image I get an error
cosign sign --key ${COSIGN_PK} ${IMAGE_UNSTABLE_K8S_TAG_VERSION}
/bin/bash: line 389: /usr/bin/cosign: cannot execute: required file not found

how to fix please tell me?

I also receive
error pushing image: failed to push to destination: HEAD unexpected status code 412 Precondition Failed (HEAD responses have no body, use GET for details)
