matterhorn: Maybe.fromJust: Nothing

[mirabilos]

My experience so far (first start) has been underwhelming…

What I did so far:

• download the latest binary release
• extract it somewhere
• symlink the binary to ~/.etc/bin/ so it’s in $PATH
• create ~/.config/matterhorn/config.ini
• start it

I got a full-screen message “Connecting to mattermost.XXX.net...” then:

matterhorn: Maybe.fromJust: Nothing

And, well, nothing. Back to the shell.

$ matterhorn --check-config
Configuration file valid
Location: /home/XXX/.config/matterhorn/config.ini

Hi, thanks for the report. What version of Matterhorn are you using, and what OS / distribution are you running this on?

Also, since it might matter - what version of Mattermost is your server running?

I downloaded the latest one, that is, matterhorn-50200.14.1-ubuntu-20.04-focal-x86_64.tar.bz2, and run this on Debian bullseye.

That’s what puzzled me, it is 6.something but there seems to be no Matterhorn 6xxxx.something release?

Would you be willing to try running matterhorn logging enabled and attach the log file here?

$ cd matterhorn
$ ./run.sh -l log.txt

As for the server version, the latest release of Matterhorn should work with server version 6, which is why we don't have a version 6 of Matterhorn yet. (But this could turn out to be an undiscovered compatibility issue; we'll see.)

I have another question: what's your value of TERM?

I’d need to anonymise a few things, if that’s okay…

``` $ cd matterhorn $ ./run.sh -l log.txt ```

There’s no run.sh, just a huge fat “matterhorn” binary.

OK.

I have another question: what's your value of `TERM`?

Feel free!

In that case, matterhorn -l log.txt will work.

“screen” (GNU screen running in xterm)

Out of curiosity, do you see the crash behavior if you run matterhorn outside of screen?

Yes, unchanged.

In that case, `matterhorn -l log.txt` will work.

Ah. The documentation (-h) is misleading here: -l PATH --logs=PATH Debug log output path This indicates a directory (in normal Unix user parlance). Using a filename works. The anonymised logfile looks as follows: [2021-11-29 13:03:15.847355281 UTC] <<< Logging start >>> [2021-11-29 13:03:15.848308686 UTC] [LogGeneral] [*] Attempting authentication to mattermost.XXX.net [2021-11-29 13:03:16.326779292 UTC] [LogAPI] [*] Function: submitRequest, event: HttpRequest POST "/users/login" Nothing [2021-11-29 13:03:16.541769199 UTC] [LogGeneral] [*] Authenticated successfully to mattermost.XXX.net as myusername [2021-11-29 13:03:16.608768299 UTC] [LogAPI] [*] Function: submitRequest, event: HttpRequest GET "/users/me/teams" Nothing [2021-11-29 13:03:16.628811284 UTC] [LogAPI] [*] Function: submitRequest, event: HttpRequest GET "/users/me/preferences" Nothing [2021-11-29 13:03:16.752107963 UTC] [LogAPI] [*] Function: submitRequest, event: HttpRequest GET "/users/me/teams/yyyzzzaaabbb/channels" Nothing Hope that helps.

Thanks for the log. On the server that you're trying this with, are you a member of a channel called town-square? (This name would be visible in the channel's URL in the browser even if its display name had been changed to something else.)

Thanks, that helps. Until this report I had not heard of Guest Accounts at all. After doing some research and talking to the server developers, we will need to do a bit of work to make sure that those work well in Matterhorn. For now, I'm sorry to say that they are not supported and I recommend you use one of the official Mattermost clients instead. I'm going to close this in lieu of #747. Thank you for reporting this and for answering my questions!

There are others? So far I only know the webinterface (first time user of this) but anything graphical is slow because it needs remote desktop whereas ssh is fast.

close this in lieu of #747.

I’ll subscribe there then, thanks. bye, //mirabilos -- Infrastrukturexperte • tarent solutions GmbH Am Dickobskreuz 10, D-53121 Bonn • http://www.tarent.de/ Telephon +49 228 54881-393 • Fax: +49 228 54881-235 HRB AG Bonn 5168 • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg

There is the official web client as well as clients for Android and iOS.

Yeah well, can only access this through a VPN on a customer-provided VM so anything not running on Debian is out. (And I can’t type on those small thingies anyway.) bye, //mirabilos, feeling old -- Infrastrukturexperte • tarent solutions GmbH Am Dickobskreuz 10, D-53121 Bonn • http://www.tarent.de/ Telephon +49 228 54881-393 • Fax: +49 228 54881-235 HRB AG Bonn 5168 • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg
