Are few months that my Nextcloud desktop client is not working.
So I was hoping that the latest release was fixing but nevermind the problem is still going.So I chosen ti compile the package on my own but... it still crashing anyway.
The cmd version is working but not the gui version and I think that is something with Qt.
Running gdb on the exectuable:

I installed also the experimental package of https://packages.debian.org/experimental/libglib2.0-0 just to see if fix the problem but it didn't.
-
a) try a new machine and a new installation
b) try pure debian
really - it isn't reproducible, if it would be there would be at least one user out of over 2500 with popcon on who will complain about the same bug.
Edit: So my best bet is that your installation is messed up - do you have any self built packges installed, no matter what - the infamous triple "configure; make; make install" or " cmake; make; make install" ??
-
I have some package compiled on myself (neovim as example) but no debian packages rebuilted.
I use KDE and a lot of qt apps but this is the only one that crashes since I think 2 months I think.
-
Starting program: /home/mte90/Desktop/(...)
That's scary. Why not from /opt?
If you need it now and you don't find the cause yet, you could (temporarily) use a daily (https://download.nextcloud.com/desktop/daily/Linux/) 2.7.0 AppImage (or the stable 2.6.1).
-
This path was from testing :-)I don't like appimage because of the huge size and because I have already all the dependence, so I more interested to understand what is the problem :-/
-
I don't like appimage
Just so we're clear, neither do I. That's why I wrote "now", "temporarily" and so on.
-
if the appimage would work - it would solve nothing - it would only mean: Hey, something is wrong with the current installation, so my bet is: Fix the mess and be happy. And there is also no magic in git builds if two versions are faulty on exactly one machine. Hmm - maybe i don't know enough about debian and Qt - i should really learn this stuff ...
-
Do you have any issue on investigating what is the problem?
Right now a ldd: https://pastebin.com/SvNQMBx5
I don't see anything wrong there for path and also the stuff I compiled doesn't involve new libraries but only specific software.
-
ok - easy to answer:
* i cant't reproduce it - so i don't care about. The packages has enough users, so if the bug would be reproducible the debian bts would be flooded with grave, important or serious bugs - nothing of that happend right now. Same for ubuntu users. Just not happend. So my suggestion is that the problem is in your installation, not in debian.
-
Just to update, I tested on my laptop where I have too siduction and the problem doesn't happen.So I am investigating more and I will open a bug to nextcloud-desktop just to understand where is the error.Because I don't know specifically what is happening.
-
Just for reference there is a bug with nextcloud on parsing the settings https://github.com/nextcloud/desktop/issues/1669
