How do I completely ininstall Lightread?

Yes, because uninstalling the app does ONLY that, it doesn't remove the configs in your home folder, the 'config files' are the ones in /etc and so forth. Uninstalling then reinstalling an application does not remove the configs in your home folder, you must do this manually.

Hence my question. Maybe someone who knows the actual paths to any relevant files and folders might now chime in.

Can you give the output of:

sudo updatedb; locate lightread | grep home; lsb_release -a

The first part of the command will take a while

Thanks

Sure. I ran the above with Lightread "completely removed" and reinstalled, and the output in both cases is as follows:

Distributor ID: Ubuntu
Description: Ubuntu 12.04.1 LTS
Release: 12.04
Codename: precise

If you run:

sudo updatedb; locate lightread | grep home

What is output (if anything), it will take a while to run

Running the above command does not yield any output (LightRead is currently uninstalled).

Does Ubuntu have some generic location to store "online account" credentials so that multiple apps can share the same logins?

try:

ls ~/.config

What is output?

Thanks

Hmm, not there, is there anything that looks like the config if you run:

ls $HOME

I'll try using the web to find the config, it must be somewhere.....

Try running:

dconf-editor

and searching in there

Okay, it's not anywhere I would have expected. Got this in an email from one of the developers:
"Lightread stores data in ~/.local/share/webkit/databases. It should be the sqlite file. We're working on fixing apt-get purge. Logout should clear all data though."

I tried both logging out and rebooting but that doesn't clear data.

I looked in the above folder, but there are multiple databases (and another folder) within that folder. If any other application other than LightRead uses this webkit folder, I wouldn't know which database to nuke. (It would be preferable, for me at least, if databases specific to LightRead were segregated in some LightRead-specific directory).

I installed sqliteman and inspected the different databases. By process of elimination, it seems ~/.local/share/webkit/databases/file__0/file__00000000000000001.db is the one that contains my login data.

Re-installing LightRead (as well as running "select * from user;" in sqliteman) confirms that neither logout nor reboot after an apt-get purge clear the login info.

Right now my only workaround seems to be to rename the webkit folder and hope nothing else besides LightRead depends on it. After doing that, and re-installing LightRead, I can confirm this does indeed hide my login info from LightRead, which creates a new webkit folder and various Sqlite databases.

I'm going to mark this question as solved. Thanks again.
