FluffyChat Encryption via Pantalaimon

slowcyclist

I have downloaded the latest click package, but struggled a bit finding how one is supposed to manually install such a click package. I did

pkcon install-local --allow-untrusted pantalaimon.thrrgilag_0.5.0_arm64.click

Then I could open launch the app, configure it, start the service. All seemed fine. However, Fluffychat does not connect through pantalaimon (" no connection "). And Fluffychat can connect directly to my homeserver.

Looking in the logs, it seems pantalaimon has a problem

Traceback (most recent call last):
  File "peewee.py", line 3035, in connect
  File "peewee.py", line 3371, in _connect
sqlite3.OperationalError: unable to open database file

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "pantalaimon", line 10, in <module>
  File "click/core.py", line 829, in __call__
 [...]
  File "peewee.py", line 3371, in _connect
peewee.OperationalError: unable to open database file
[11864] Failed to execute script pantalaimon

I suspect the way I installed the app might not give it the proper rights to operate correctly. If so can anyone tell me how one is supposed to properly install a click package manually? Otherwise, any idea how I can debug the issue?

@slowcyclist
Ubuntu Touch Tweak Tool have a built in feature to install click packages.

Hey thanks @keneda, problem solved! I wish that piece of information were more obvious...

@thrrgilag would it be easy to include panctl into the click so that people could verify the device on command line at least? I see that it gets built with pantalaimon already, but not packaged.

thrrgilag

@jonius as I recall it builds but doesn't necessarily run. But it's been a while so I don't recall exactly what the issue was. I'll take a look again when I get a moment and see what I can get working.

@thrrgilag hello, i am using fluffychat with pantalaimon. I have the issue with pictures are not shown in the preview (or aactually at all) on my device . could you please let me know what to do?

thrrgilag

@hugehead The image loading issue should have been resolved with the last update to FluffyChat. Can you share some specifics about your setup?

Device
Ubuntu Touch version
FluffyChat version
Pantalaimon-UT version

Hey,
after successfully using this nice application for a longer time without any big problems I switched my home server and now I have problems to login correctly.

I was able to login two times after resetting everything. But after a reboot I am always back to the Fluffy login screen. When I then login, Fluffy says sth. like "no connection" and there is an empty account opened with no chats or data. This always creates a new Fluffy Chat login session on my Matrix account but there is just a single Pantalaimon session visible.

When I was loged in successfully futhermore I wasn't able to activate encryption. Messeges send from the Phone were always taged to be unencrypted.

Do you have any Idea what could cause this problems? Maybe its also related to my homeserver configuration as it was working perfectly before.

Thanks for your help,
JimmyPesto

@jimmypesto could be something left over from the old connection confusing things. Try doing the following.

stop and disable pantalaimon
delete or rename /home/phablet/.local/share/pantalaimon
enable and start pantalaimon
login through fluffychat

And if that's all good try another reboot to ensure it comes remains logged in.

A Former User

@thrrgilag thanks for that super quick answer!

Steps i followed:

disabled pantalaimon
Opened adb shell to
sudo rm -r /home/phablet/.local/share/pantalaimon
added my homeserver again to pantalaimon
enable and start pantalaimon
login with fluffy (successful login, but still no encrypted messages send to other element clients)
reboot
open Fluffy which is still online, nice, I hope it will last now

But still all encrypted conversations receive unencrypted messages from my phone. At least Element says so.
I set the pantalaimon session to be trusted from Element and I enabled all other devices in Fluffys encrypton settings of different rooms.
Even though I can read messeges inside encrypted rooms, I can not find a way to get rid of that "not encrypted" warning sign. I am confused.

thrrgilag

@jimmypesto okay I'll see if I can reproduce and report back if I have an answer of any sort. If you could see if there is anything useful in the logs, I'm guessing not but worth a shot.

@thrrgilag what log files should I check exactly? What log level should I select inside Pantalaimon?

I have another issue of chats with peoples devices that are verified but still I get a grey icon and I can restart the verification over and over again. Seems like a big mess going on. I dont know if thats because of Pantalaimon or sth is messed up on my homeserver side.

Greetings

@jimmypesto there are two log files, one is labeled as pantalaimon-ut which is just the configuration UI, and the other one is called pantalaimon which is the deamon that does all the work so that's the one to look at. You can use the Logviewer app from the openstore to access them easily.

Unfortunatly I haven't done any testing on it since my main ubuntu touch device stopped booting. I'll have to get that sorted or another device up and running before I can work on it further.

thrrgilag

@jimmypesto I've been able to get my ubuntu touch devices back up and running and I can reproduce the problems. Unforunatly I don't have a fix yet but I'll work on that and see what I can come up with. Likley will be a new version of the package if I can get a newer build functional.

There are moments when I wonder if it'll just be easier to add encryption support directly into FluffyChat QML but time is a luxury I don't have.

Pantalaimon UT 0.6.0 released

This is an important bug fix release which resolves an issue with messages sent as unencrypted in encrypted rooms. Please update and restart the pantalaimon service.

As an aside, although I'm not a regular user of Ubuntu Touch these days I do intened to keep supporting this for a while so do let me know if things go sideways again and I'll do my best to stay on top of it. In addition to this thread feel free to contact me directly, hit me up in public chat, or the mailing list.

A Former User

@thrrgilag hey thanks for all your feedback, your support and the bugfix. I wasn't able to answer until today and will test v 0.6.0 now.

Integration into FluffyChat would be super awesome. I would love to contribute to this but idk. if I can adept to this kind of app development. At least I would love to donate for that.

[EDIT]
So I updated to v 0.6.0 and still have the following problem which kept me from testing the encryption thing thang:
When I have bad internet connection, sometimes I get loged out inside Fluffy. (happend already with v 0.4.x if I remember correctly)
Inside an other Element session, the settings still show a Pantalaimon and Fluffy session. I delete these sessions.
Regardless of restarting Pantalaimon or not, when I now login inside Fluffy, I get to an empty start screen with no chats, no name, no pic, nothing. (Typing wrong login data gives me correct feedback msg about it.)
When I look into the active sessions from Element, I can see a Fluffy but no Pantalaimon session.

Pantalaimon log [lvl warning] ends with:

socket.py 752 getaddrinfo

LookupError: unknown encoding: idna

Unclosed client session

client_session:
<some object and Address>

A minore usage difficutly that I encountered:
When you add a homeserver, type in the HS URL and directly hit [save], without leaving the text-box before, the HS URL just typed in is forgotten. This could be more fool prove, but Its not really a big thing.

Greetings.

@jimmypesto I'll do some testing on the connection thing, I pretty much have only done testing on WiFi so I didn't catch any issues around lost connections yet. Sounds like it might also be helpful to include a reset button of sorts, to clear the db when the session gets lost to it can be redone. I'll also take a closer look at that UI bug, seems odd that would happen.
