Subject of the issue

I've set up a cronjob to backup my SQLite DB as the documentation suggested.

But sometimes I can't read the DB and get the error "Error: attempt to write a readonly database" when trying a simple .tables command against it.

I've found that it happens when I reboot my system, and maybe when the app has been unaccessed for a while.
The reliable thing I found is when the DB is unavailable, there are no db.sqlite3-shm and db.sqlite3-wal files next to it. When they are present, I can read/write my DB via sqlite3.

The simple fix I found is logging in, then I guess a log session is wrote and the DB is "unlocked".

What can be done about it to be able to reliably access my DB?

PS: I've found #1404 but it doesn't seem to apply to my problem.

Expected behaviour

I'd like to be able to backup at any time.

Actual behaviour

I need to do operations on my app first (such as login) to be able to backup.

Thank you! :)
