What I'm trying to do and why

Create backup using borgmatic docker version 2.1.6

Steps to reproduce

Update borgmatic Docker container from 2.1.5 to 2.1.6
Borg repo in remote location using ssh
Config:

source_directories:
    - /mnt/source/nginx-proxy-manager
    - /mnt/source/nextcloud/nextcloud
    - /mnt/source/nextcloud-staging/nextcloud
    - /mnt/source/pihole
    - /mnt/source/home-assistant
    - /mnt/source/portainer

repositories:
    - path: ssh://matias@192.168.0.17:22/media/BackupDrive1/borg-repositories/raspinator
      label: raspinator
      encryption: repokey-blake2

keep_daily: 5
keep_weekly: 3
keep_monthly: 3

checks:
    - name: archives
      frequency: 1 week
      only_run_on:
         - Friday
    - name: repository
      frequency: 2 weeks
      only_run_on:
         - Thursday
    - name: extract
      frequency: 1 month
      only_run_on:
         - Monday
    - name: data
      frequency: 1 month
      only_run_on:
         - Tuesday

verbosity: 2
statistics: true

mariadb_databases:
    - name: nextcloud-db
      label: nextcloud-db
      hostname: nextcloud-db
      port: 3306
      username: /run/secrets/db_user
      password: "{credential container mariadb_password1}"
      password_transport: environment
    - name: nextcloud-db
      label: nextcloud-staging-db
      hostname: nextcloud-staging-db
      port: 3306
      username: /run/secrets/db_user
      password: "{credential container mariadb_password2}"
      password_transport: environment

sqlite_databases:
    - name: memos_prod
      label: memos-db
      path: /mnt/source/memos/data/memos_prod.db
    - name: docker-app-updater
      label: docker-app-updater-db
      path: /mnt/source/docker-app-updater/docker-app-updater.db

run inside the docker container: borgmatic --stats --verbosity 1

Actual behavior

After the first password prompt (archive step) borgmatic throws stacktrace:

I've noticed I'm missing the volume mount of /root/.local/state/borgmatic in the docker compose. But according to the stack trace the problem is with the .cache directory.
Here my docker compose:

services:
  borgmatic:
    container_name: borgmatic-app
    image: ghcr.io/borgmatic-collective/borgmatic:2.1.6
    volumes:
      - ${VOLUME_SOURCE}:/mnt/source:ro # backup source

      - ${ENVIRONMENTS_BASE_PATH}/.config:/root/.config/borg # config and keyfiles
      - ${ENVIRONMENTS_BASE_PATH}/.ssh:/root/.ssh # ssh key for remote repositories
      - ${VOLUMES_BASE_PATH}/.cache:/root/.cache/borg # checksums used for deduplication
      - /var/run/docker.sock:/var/run/docker.sock
    environment:

    secrets:

Seems like the volume is already beeing added to the template docker-compose in https://github.com/borgmatic-collective/docker-borgmatic/pull/392

This stack trace is actually coming directly from Borg, and I'm not sure what's causing it. It's especially weird if a downgrade of the container fixes it, since I think both versions of the container contain the same version of Borg. But here are some ideas on things to try:

You could try deleting (or temporarily moving aside) the contents of your Borg cache directory on the host (${VOLUMES_BASE_PATH}/.cache/*) to see if that "fixes" the problem. Your first backup afterwards will be slower though as Borg regenerates the cache.
It may be helpful to see the source patterns that borgmatic is writing to the patterns file being passed to Borg, in case that provides any clues as to what's going on. You can find those patterns in your borgmatic logs after the Writing patterns to ... line.
If you want, you could try running Borg directly without borgmatic to see if the problem still occurs (in each of the 2.1.5 and 2.1.6 containers). You can see the exact Borg command that borgmatic is running at the end of your logs above. You'll have to remove the --patterns-from ... portion though and replace it with all of your source directories directly on the command-line.

Oh, and missing the state directory just means that borgmatic won't be able to record when checks last ran—and thereby won't be able to run checks at the frequency you're requesting (they'll run more frequently). So you should definitely add a volume for the state directory, but not having it shouldn't cause errors.

Seems like I misdiagnosed the issue. I checked the logs and the update to 2.1.6 was running fine. The real issue seems to be the messing with the commands the other day, to send notification when backup starts/stops. Some commands where not valid and threw errors, that probably corrupted the cache.
Sorry for the false reporting and thank you for the project, it really makes using borg easy.
I will change the issue title to represent the real problem.

Seems like I misdiagnosed the issue. I checked the logs and the update to 2.1.6 was running fine. The real issue seems to be the messing with the commands the other day, to send notification when backup starts/stops. Some commands where not valid and threw errors, that probably corrupted the cache. Sorry for the false reporting and thank you for the project, it really makes using borg easy. I will change the issue title to represent the real problem.

The solution was probably not downgrading to 2.1.5, but just restarting the app / clearing the cache.
