Prerequisite: Appearance of Plasma Crash Reporting Assistant. Step to reproduce: 1. Select 'Developer Information' tab. 2. Click on 'Install Debug Symbols' button. Expected result: Installation of debug symbols. Actual result: Popup 'Missing debug symbols' window appears with text 'Requesting installation of missing debug symbols packages...' - and after some time 'Error during the installation of debug symbols' window appears. Also timeout for this error message is not strict - sometimes error appears in about 10 sec and sometimes looks like it never appears.
when an error occurs grab debug output from ~/.cache/xsession-errors and post it please. I am not sure what exactly you want to happen though. If there's an error there's an error.
1. Start Wayland session on unstable live iso - currently it's 20170813 iso. 2. Cause some Plasma Wayland crash. 3. Click on 'Plasma Closed Unexpectedly' icon in system tray. 4. 'Plasma' window with 'We are sorry, Plasma closed unexpectedly...' text in 'General' tab of this window appears. 5. There's also 'Developer Information' tab in this window - and in this tab there is 'Install Debug Symbols' button. 6. After pressing on this button - 'Missing debug symbols' window appears. After some time 'Error during the installation of debug symbols' popup window appears. Debug symbols are not installed.
Live sessions cannot install stuff as they have no apt cache.
I think that this is major issue - without debug packages i cannot easily send bug report with backtrace through Crash Reporting Assistant after a crash both in X and Wayland. Or am i missing something?
Debug reports from live sessions are fairly useless. Live sessions are mostly non representative as the system is bootstrapped out of UEFI in fairly non-standard ways, drivers may not be available/loaded and the running applications themselves are restricted/crippled as to conserve RAM usage seeing as both the ISO/delta thereof and the application need to fit in RAM. It works just fine once the system is installed.
I have neon dev unstable installed on my hardware, drkonqi never installs debug symbols package. I need install it manually.

there is no ~/.cache/xsession-errors file under Wayland.
~/.cache/wayland-errors
I get "No such file or directory"

(In reply to Harald Sitter from comment #17) > In fact, your cache isn't either, you should be getting +git20170820 or > later as candidate. This is default policy after update of the system with Discover in Dev Unstable iso. How to change this policy? Should i report a separate bug on this issue?
What policy? You need to update your system.
I installed 'libqalculate6' package - cause without it plasma workspace wasn't updating. After update and reboot - i got the following output in apt-cache policy: Installed: 4:5.10.4+p16.04+git20170816.0342-0 Candidate: 4:5.10.4+p16.04+git20170816.0342-0 Version table: *** 4:5.10.4+p16.04+git20170816.0342-0 500 500 http://archive.neon.kde.org/dev/unstable xenial/main amd64 Packages 100 /var/lib/dpkg/status 4:5.5.5.2-0ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages
Any progress about this problem? "Install debug symbols" button is useless and never installs debug packages. End users need a crash reporter that works to send good backtraces and help devs to improve KDE software.
*** This bug has been marked as a duplicate of bug 395757 ***
Is it can be wrong duplicate marking? - crash on connect to WiFi and debug symbols installation problem
