Backup of Signal messages stopped working after updating to SFOS 4.5.

I suspect this is a problem with users/uids groups/gids that have changed. When I check the backup from before the update, the user/group it was created with doesn’t exist anymore.
[Edit 1]: I was right with my suspicion. This seems to be a general problem with user/group-rights for android artifacts after the migration. Related to: 4-5-0-16-10ii-android-app-audible-is-unusable-saying-sd-card-requiredPreformatted text
[Edit 2]: I think I’ve solved the problem although I wasn’t successful yet in performing a backup. But at least after turning off backup Signal cleaned the old backup files as expected this time. There is a backup scheduled during the night. I’ll give a heads-up tomorrow. What I did so far:
- Find the group that is used by android apps in sailfish now:
[root@JollaBart android_storage]# getfacl /home/defaultuser/android_storage/ # file: home/defaultuser/android_storage/ # owner: 501023 # group: appsupport-media_rw user::rwx group::rwx group:defaultuser:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:defaultuser:rwx default:mask::rwx default:other::---
- chown and chmod the directory for the backup on the SDCard recursively:
[root@JollaBart android_storage]# chown -R :appsupport-media_rw /run/media/defaultuser/1ae588c3-0da0-44f9-97c6-e3e2f496efdc/Signal [root@JollaBart android_storage]# chmod -R g+rw /run/media/defaultuser/1ae588c3-0da0-44f9-97c6-e3e2f496efdc/Signal/ [root@JollaBart android_storage]# ls -ld /run/media/defaultuser/1ae588c3-0da0-44f9-97c6-e3e2f496efdc/Signal/ drwxrwxr-x 2 media_rw appsuppo 4096 Feb 14 17:11 /run/media/defaultuser/1ae588c3-0da0-44f9-97c6-e3e2f496efdc/Signal/
