running out of ideas, tbh 
which version of defender? .72 or .73?
for 72:
cat ~/.config/harbour-defender/error.log
for 73:
cat ~/Documents/.defender_err.log
-
or just pulley menu, show error log
some other host modifier reverting the change immediately?
No, nothing. I’ve never done anything with my hosts, but manually update Steven Black lists.
Error log is not much use. All the time it says…
INFO: update was still running - cancelled
…no more, no less.
For now, I give up and will reflash my C2 and try again.
Finally… with newly flashed C2, it seems to work as intended, but only after I removed and reinstalled Defender twice. 
I have no idea why. Never got any error log or other hints.
That means the update was still running…
…AND you canceled the update loop from menu
(I have seen it as well taking more time even it was only one list, have you been in a hurry? 
)
Procedure is
Either fetching the lists
Or packing them together in one
Or writing
Yay!
At least it works!
But what might have caused this is totally over my head…
Iirc I had this as well when installing first time on my test XA2, but not after having it re-installed!?!!!
But, in general it should be okay to push this to stable?
Well, I think so, even if other users might run into same mysterious issues.
The Adblock List area, what is that good for?
What do you mean?
Selecting the desired advlock lists from different internet sources to be merged into one hosts file?
Perfect.
If you would like (or more: would be so kind) to reflash/reset your C2 once more?
I thought and might have a last straw that might have caused that behavior (even we did not need it before).
Then I would prepare a .74 version and put it into testing
Wouldn’t it be enough to remove Defender and all conf/tmp/var files?
I just finished to set up device with all I need for testing. Took most of the day. 
I just took a chance with my daily drive (X10III) and did a really good clean out from Defender remains, and installed .74… and it worked! 
What changes did you do from .73 ?
Edit:
Found it…
v0.7.4
- added the systemctl daemon-reload after installation (hopefully resolving the strange behaviour after first installation, see @eson)
Woohho. Nice.
Then I will request to get Defender out in the wild!
Thank you very much @eson
Next thing to test will be a SAILJAILED version. 
I could as well improve some more err log outputs.
And remark, that an empty cookie list may be due to a still open browser (or might kill it and restart after mission completed? - or just as pulley menu?)
Oh, and cleaning up borken sqlite do status.
And new or obsolete (e.g. OISD) hosts lists. But for this I need input from community
You can safely remove also MVPS Hosts. Very much outdated.
Do you want translations? Because I couldn’t fork your repo.
Sadly yes.
Will do that in next version
And same for OISD, not anymore available as hosts format
And need to check some download links (for GoodByeAds) and others as well.
Probably adding UHB Ultimate Hosts Block
Anything else?
Oh, I do not know.
I remember having seen some of those qsTr strings and tried to go with them further but have no clue how to really make use of them 
And no one bothered, asked for translated app.
But hey, why not? If it is easy and someone can tell me, sure
Why did you want to fork? Isn’t cloning the way to go for?
And another why? No idea why forking did not work for you. What was the error message?
I did not setting any restrictions on that repo.
And another thing

I can proudly announce:
Defender v0.7.4
is available on Chum
–
And, I think, we should leave this here as is and keep talking on old Defender from here on
@pherjung @filip.k I would close this thread here?
Or merge it or parts to above?
–
Oh, , and one more…
No, not that slang 
On testing is now v0.8.1 in a sailjailed version, else fumctionality-wise same as the one in release channel.
Someone else wants to try? You would be the first, I am going to sleep 
There is a procedure to integrate translations on chum that I do not remember, but I think anyone with a translated app on chum can help.
I have already tried with Swedish translation on my C2 and it works.
Well, there are some strings that do not translate, but that can be fixed.
About the fork, I was trying to fork on GitHub, to make a PR on translation, but got the error message…
An unexpected error occurred. Please try again.
…now it worked.
Edit:
Not on chumGui! There’s still 0.7.4
v0.8.1 is available if you have setting Testing Repository set to true chum → Pully Menu.
I have installed this version (v0.8.1), but after Sailjail Dialog, the app does not start, i hab an old version installed before . I cleaned config file and did a fresh install as well. But app will not start.
It wasn’t this morning, because OBS building failed.
