For people not using redis: there is now an "automated patching mechanism" that will instead use the next best fork of redis that is available on your system as the Requires= dependency in *.service. This way, anyone can use their favorite fork of it. Keep in mind that upstream does not explicitly say that forks of redis work as well, and this further makes the built paperless-ngx-venv package non-portable. Happy experimenting :)

Finally the update to 1.14.0 has been pushed and it should install just fine. A few dependencies got added, a few of which I also had to package first.

Note that python-billiard still needs to be downgraded to 3.6.4 until celery catches up... The next stable release of celery will include the compatibility fix for billiard 4 which has already been pusblished as pre-release a year ago

@amo: thanks for the hint. I actually haven't thought about using AUR for the downgrade. But I also realized that there are a lot of mismatches between pip versions and pacman/AUR.

Besides I am waiting for the next version before I post an issue at github. My /tmp directory gets filled by ocrmypdf.io.### entries which are not cleaned up automatically. Docu says this behavior is when "-k" switch is used. But that doesn't seem to be the case. I ran into "disk out of space" problems system wide, until I used an additional timer script that checks and removes unaccessed paperless directories inside /tmp after 2h.

@Tweety: What pip did for you is downgrading billiard, which you are supposed to do anyway at the moment. The more consistent way of doing this is to use the downgrade AUR package instead of pip.

Hi amo,

just to confirm lorner's comment regarding celery.

Had to "pip" manually before things started to run on a second installation (first one was ok without it).

Procedure to check and repair:

### Check systemd Service:
systemctl status paperless-task-queue.service
× paperless-task-queue.service - Paperless Celery Workers
     Loaded: loaded (/usr/lib/systemd/system/paperless-task-queue.service; disabled; preset: disabled)

### Get python pip
pacman -S python-pip

# Credit to lorner
sudo pip3 install billiard==3.6.4.0 

# Tweetys approach - automatically fetches billiard 3.6.4.0
sudo pip install celery
...
...Collecting billiard<4.0,>=3.6.4.0
...

systemctl restart paperless-task-queue.service

Hope that will be fixed in 1.13 :)

@DocMAX:

not really helpfull your post. When do you get that error? Output of ls -l /etc/paperless.conf

PermissionError: [Errno 13] Permission denied: '/etc/paperless.conf

And i did sudo -u paperless paperless-manage migrate

@Tweety: Yes, you are right with the missing optional dependency. I added it and it will figure in the next update. Thank you.

As for the documentation: For PAPERLESS_DBSSLMODE, there is a link you can follow and which leads to a table listing and explaining the possible options. PAPERLESS_CONSUMER_BARCODE_STRING is simply a string which means that any sequence of characters should work, but I don't really know how to use separator barcodes or how exactly they work. PAPERLESS_LOGROTATE_MAX_SIZE is to be given in bytes according to the documentation, so for 1 MiB you could also simply put 1048576.

Anyway, if you feel like the documentation could be improved and you even have suggestions on how to improve it, why not contribute by creating a pull request? This is all the magic of open source!

@amo

I am using mariadb for some other applications, so I wanted to use that for paperless too. I stopped the tests after I was finally able to log into the system. Connection to MariaDB seems to run properly now but further configuration and tests with scan/documents will follow later. Maybe expressed badly from my side. I wanted to provide the hint, that python-mysqlclient is necessary but not mentioned in the dependencies (optional).

For example

PAPERLESS_DBSSLMODE=<mode>
default is <prefer> 

PAPERLESS_CONSUMER_BARCODE_STRING=PATCHT
default is <PATCHT> 

PAPERLESS_LOGROTATE_MAX_SIZE=<num>
Defautl 1 MiB --> what number format in MiB, MB, KiB, KB? 1GiB entry possible?

No other values mentioned. Some other options are similar undocumented.

However. Hope that it runs now and I can move on to tika/gotenberg setup. [EDIT]: doest not.. - any hints where to correct dependency libavformat.so.60 to .59? <- solved

MissingDependencyError: Ran program 'unpaper' but it exited with an error: unpaper: error while loading shared libraries: libavformat.so.60: cannot open shared object file: No such file or directory 

[EDIT]: seems like ffmpeg was not updated while using yay for paperless. Solved that by updating ffmpeg-2:5.1.2-1 manually to ffmpeg-2:6.0.3. Should that be somewhere at the dependency check?

Sorry for texting ;)

@Tweety: I didn't find the documentation to be missing possible values or to leave something unexplained. Which config-entries are you having trouble figuring out?

I haven't tried to make paperless use mariadb yet. I like that it's apparently possible, but the fact that paperless is single-user makes me feel like sqlite should handle even production load easily. Anyway, didn't installing python-mysqlclient solve the dependency issue?

Hi amo

... glad to hear you happily passed your examinations ...

stupid question from a paperless newbie: I am setting it up for the first time but have got a LOT of difficulties to find possible values for many of the config-entries. The https://docs.paperless-ngx.com/configuration/ docu simply tells the default values but all other possible values are not listed. Compared to other config-files (sample configs) where a parameter is listed and above well documented, paperless is -at the moment- really a pain.

Any hints?

Additionally I want to use mariadb. That doesn't work ootb because required dependency is missing:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

pacman -S python-mysqlclient
