Completely reinstalling mnemosyne

[bitt...@gmail.com]

I was messing around with Mnemosyne, and now it opens a dB in a folder on a USB that I no longer have, so Mnemosyne looks for that folder, and gives me errors when picking another DB. Luckily, I have a back up of my db on my main disk, so I can use the -d feature to open that specific folder, and all my cards are restored. This is a minor hassle, so is there a way to fix this and get it to work again? I've tried deleting Mnemosyne and reinstalling it.

The location of the last saved file is in 'config.db', so deleting (or editing as an sql database) should work.

Recent versions of Mnemosyne shouldn't give problems to open a different database if the old one is no longer there, though.

Cheers,

Peter

Hi Peter:

I can't delete the config.db because I don't have the drive with the original db on it. I have ran mnemosyne with -d option, with my newdatabase. This gives me a config.db, but deleting it does nothing. Here's the error that I got:

Traceback (innermost last):

Thank you.

On linux, the default config.db that is used when you just type "Mnemosyne" should be under ~/.config/mnemosyne/. It is there that the last saved database is encoded.

If you get 'permission denied' when using the -d option, that seems to suggest you don't have permission to create new files in that location.

Also make sure you are using the latest Mnemosyne version.

Cheers,

Peter
