Hi all.
I have been trying to test the solution but I'm getting this error when I upload a file.

From the webserver, it shows upload successfully. However, If click on the analysis page, it shoes the file does not exist.

I followed this instructions:
$ docker pull ghcr.io/fkie-cad/fact-core-frontend:4.0.1
$ docker pull ghcr.io/fkie-cad/fact-core-backend:4.0.1
$ docker pull ghcr.io/fkie-cad/fact-core-scripts:4.0.1
$ ./start.py pull
$ ./start.py compose-env
--firmware-file-storage-dir path_to_fw_data_dir
# Have a look if it looks right
$ eval $(./start.py compose-env --firmware-file-storage-dir path_to_fw_data_dir)
$ export FACT_DOCKER_POSTGRES_PASSWORD=mypassword
$ docker volume create fact_postgres_data
$ docker-compose up -d database

Wait some seconds until the db is ready

$ ./start.py initialize-db
--network fact_docker_fact-network
$ docker-compose up

The last command shos this warning:

fact-backend_1 | [2022-11-17 04:09:22][start_fact_backend][WARNING]: Could not change permissions of docker-mount-base-dir. Ignoring.

My Linux system is
Linux 5.15.0-53-generic #59-Ubuntu SMP Mon Oct 17 18:53:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux.

I appreciate any indication/help

Thank you.

What did you set path_to_fw_data_dir to?
Maybe it is not clear but path_to_fw_data_dir in the instructions shall be replaced by some path on your system.
E.g. $HOME/fact-firmwres (which you have to create before ofc).

fact-backend_1 | [2022-11-17 04:09:22][start_fact_backend][WARNING]: Could not change permissions of docker-mount-base-dir. Ignoring.

This warning can be ignored if I'm not mistaken. The docker-mount-base-dir is a directory in which all files that shall be mounted by docker must be placed by FACT. If you didn't change this in the default configuration this should be fine as the permissions are set right by start.py.

Hi @maringuu
Thank you for your answer.
I have created a local path at /media/data/.
The user is part of docker group.
I changed the permissions to 777. No ideal but I am able to test it.
chmod -R 777 /media/data/
I had to change the permission to 777 at /tmp/fact-docker-mount-base-dir
chmod 777 -R /tmp/fact-docker-mount-base-dir

The tool is working now.

Thanks

The tool is working now.

Nice to hear!

Changing to 777 should really not be necessarry.
When I have time I'll investigate further what the problem ist.
