Hi,
the error is produced when the script executes the following command (turns the maintenance-mode off):
docker exec -it docker_app_1 su -s /bin/bash “www-data” -c “php occ maintenance:mode --off”
because this is the first command which wants to change something on the running Nextcloud - but Nextcloud is not running.
this is my script:
#JUST STARTING THE PROCESS IF THERE IS A BACKUP TO RESTORE
cd /var/lib/nextcloud-backup/backup/
lastbackup_1=$(ls -Art tail -n 1)
if [ -z “$lastbackup_1” ]; then
echo “THERE IS NO BACKUP TO RESTORE”
else
#STOP AND DELETE THE RUNNING NEXTCLOUD
#STOP THE RUNNING CONTAINERS
docker stop docker_db_1
docker stop docker_redis_1
docker stop docker_cron_1
docker stop docker_app_1
#REMOVE THE RUNNING CONTAINERS
docker rm docker_db_1
docker rm docker_redis_1
docker rm docker_cron_1
docker rm docker_app_1
#DELETE THE VOLUMES
cd /var/lib/docker/volumes/
rm -r docker_nextcloud
rm -r docker_nextcloud_db
#GENERATE NEW EMPTY FOLDERS FOR THE NEW VOLUMES
mkdir -p docker_nextcloud/_data
mkdir -p docker_nextcloud_db/_data

rm -r nextcloud.yml
rm -r db.env

#SEARCH THE NEWEST BACKUP

lastbackup=$(ls -Art tail -n 1)
#COPY THE DOCKER-COMPOSE FILE FROM THE NEWEST BACKUP BACK WHERE IT USED TO BE
cp /var/lib/nextcloud-backup/backup/“${lastbackup}”/config.tar.gz /home/ubuntu/anivo/docker/
#UNPACK THE .tar.zip FOLDER WITH THE DOCKER-COMPOSE FILE AND REMOVE THE DOCKER-COMPOSE FILE
cd /home/ubuntu/anivo/docker/
tar xfvz config.tar.gz
rm -r config.tar.gz
#START THE DOCKER-COMPOSE
docker-compose -f nextcloud.yml up -d
#STOP THE RUNNING CONTAINERS

#REMOVE THE NEW GENERATED VOLUMES
cd /var/lib/docker/volumes/
rm -r docker_nextcloud
rm -r docker_nextcloud_db
#COPY THE VOLUMES FROM THE NEWEST BACKUP TO /var/lib/ (DEPENDS ON THE DOCKER-COMPOSE FILE), UNPACK THE FOLDERS AND REMOVE THE .tar.zip FOLDERS

tar xfvz docker_nextcloud_db_backup.tar.gz
rm -r docker_nextcloud_backup.tar.gz
rm -r docker_nextcloud_db_backup.tar.gz
#START THE DOCKER CONTAINERS AGAIN - NOW THEY USE THE VOLUMES FROM THE BACKUP
docker start docker_db_1 docker_redis_1 docker_cron_1 docker_app_1
#IN THE BACKUP THE MAINTENANCE-MODE IS ENABLED - NOW YOU NEED TO TURN IT OFF
docker exec -it docker_app_1 su -s /bin/bash “www-data” -c “php occ maintenance:mode --off”
Overall I am setting up a new Nextcloud where the new generated volumes are replaced with them from the backup.
This file is executed via a cronjob - mybee there are some differences to when I am executing this file manually with ./… .
However, I just found this question:
seems like this guy has the same problem than me, but in my case it worked before - why should now the php version be the problem.
