Defender app update (harbour-defender) - my very own ‘Sailfish Devember’

Yes, I know.
But why the browser still works (okay read something that browsers might survive / overcome this)
But openssl ? Should this not be affected as well?

I know that Firefox has its own certificate store, it does not need the OS for the certificates.

I assume the last paragraph is you looking for ideas so let me share mine. You could stop updating and hide progress replacing it with an error message there was a wrong source. Even better, also display which source. Even better, add a button offering to disable the particular source and continue.

I have some tips for using Defender.
First is that it takes many times more to update than you are expecting. I am using just 3 lists of Goodbye Ads, and it still takes an hour to finish. But I have to say, if I let it do its thing, it does work reliably and always complete.
Second is that if you want it to be done fast, is to keep your screen on. My Xperia 10 lowers its CPU clock by a lot when screen is off, and that increases the time. So it takes much more than an hour with the screen off.
And you can check in htop or lighthouse if there is a python process using a lot of CPU. If there is, then it is still updating and you simply have to wait more.
So thank you so much Peter for keeping this app updated, it is very reliable, you just need to have a looooooot of patience.



Implemented a quick fix for the failing source and activated all sources and tapped update.
That was somewhat in the evening (around 8 or so). I locked the device and put it on charger.
Next morning I checked it again and it just finished shortly after 0700.
So the update with all sources may take up to 12 hours!

Leave it running.
(for now deactivate

I will push that fix which will catch the certificate exception and let the update continue in a few days.
So either believe that update message means it is updating. Or check whether
ps aux | grep defender_updater

yields a match. If it is there it is still running.
If not pull the pulley menu and tap ‘show error log’ (soon™ to come :wink: )


This is great! If you prevent any error from blocking the process, then there’s no need for messages as I suggested.

Important info

The blocking of names/IPs for the dark side (android) container may not work at all.
Really sorry (but you may understand I forgot about it).

Please see here (and also there).
As said I will try to get a fix for that into the defender package but it might need some testing and therefore time.


Looking forward to this upgrade! I haven’t updated the lists in at least a month, the ads in youtube have started to annoy me.

Just a question from a noob. Why does it actually take so much time to update the resources?

Good question!
Answer from a I-just-took-over-and-tried-to-fix-boot-problem-noob:
No idea!

One would need to look deeper into the used python hosts library and check for nested loops (something python is not good in?).

And tbh I really did/do not care enough to spend time into this. :wink: (this only arouse after adding more huge host files)

Thank you for the answer.
It’s perfectly understandable.

I was asking this because usually when using AdAway on Android, it takes a couple of seconds for those lists to get updated. On SFOS as well (if one is using a script from openrepos called Hosts Adblock). I kinda though that these apps/scripts would help you out with the project in the long run.

Selecting only AdAway (as well as selecting other sources separated) on its own is also quite fast, as long as you do not try to merge other sources.
If you only select one source it is normally a matter of less than a minute. (and it is only not a few seconds as defender always tries to eliminate duplicates)

AdBlock is the predecessor of Defender (when you look at the icon and the original developer :slight_smile: ).

Idea for some additional lists to be included in the future:

Source = oisd_dbl
Name = oisd_dbl_full
Info =
Url =
Description =
License =
SourceEnabled = no

Or DeGoogle your life:

Source = Nick
Name = De-Google Life
Info =
Url =
Description = Special List to Block Google
License =
SourceEnabled = no

The first one blocked some metrics trackers used by Pandora that where not blocked by the current lists.


I’ve tried it out and it works amazingly well. It’s actually quite fast if you select only certain lists.
Well done, Peter!

Would it be possible to block the initial ad that starts before some YouTube videos? I can see that is blocked in those lists but maybe it’s necessary to include as well?

About those ads at the beginning I have no idea but think that goggle is clever enough to not let us block those that easily.

You want to watch videos but block the source (

So, that’s what it would do. Sorry, I didn’t realize that.
Nevertheless, it’s working great with everything else, so 4 seconds of commercials is something I can live with. :smiley:

As per my understanding YouTube ads cannot be blocked with lists. But what you can do is download Firefox and install uBlock and I have never seen any ads again.

You are right, this is indeed the case. The thing is, I’m trying to use Android apps only when necessary.
Hopefully, Jolla Browser will support Firefox extensions one day.
I’m really satisfied with SFOS in general, I only miss small things here and there.

@peterleinchen I saw the notification about an update yesterday and installed immediately after. I still had to leave the device updating over night but it did finish this time. So I have 1284000 sources and I’m content. Thank you.
Nevertheless, I still have my suggestions but you’ve disabled issues in github. What’s the preferred way for you to receive reports?

@peterleinchen Not sure why, but I can’t see the new oisd host source in the latest version 0.5.7 (it’s in the source code in github).
