Bug ID: 466061
Summary: The generated crash information is not useful Possible
cause: repository 'http://ddebs.ubuntu.com
$(lsb_release Release' lacks a Release file [Ubuntu
Studio].
Classification: I don't know
Product: kde
Version: unspecified
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org

Target Milestone: ---
SUMMARY
***
I wanted to supply a backtrace with my report of a Plasma crash in Ubuntu
Studio.
What happened is I am unable to attach a backtrace with debug symbols.
Receiving instead "The generated crash information is not useful"
Confused about whether Ubuntu Studio 22.04 had the DEBUGINFOD_URLS function I
attempted to install the dbgsym-packages.
Then found following error which might explain why I was receiving the above
error message.
"E: The repository 'http://ddebs.ubuntu.com $(lsb_release Release' does not
have a Release file.
N: Updating from such a repository can't be done securely, and is therefore
disabled by default.
I am puzzled that after receiving the message
"I: All needed dbgsym packages are already installed."
the automatic report system has been disabled in this case.
I admit in attempting the following procedures I found myself confused at
times.
I have saved most of what command line work and results if that might clarify
where I went wrong, if I did.
So any help in ensuring that I do have a working DEBUGINFOD_URLS function for
the next crash whether Plasma or other applications, would help me to help you.
***
I encountered this error while attempting to report a Application: Plasma
(plasmashell), signal: Segmentation fault
However in attempting to produce crash information I kept getting
"The generated crash information is not useful"
The KDE Crash Handler listed these as missing.
/usr/bin/plasmashell

Am I in error in assuming the above list is the same as those in, "I: All
needed dbgsym packages are already installed."
I tried and was unsuccessful in finding the [.so.5] versions listed in Synaptic
Package Manager
I used "kstart5 plasmashell" to restart plasma and I followed the instructions
in the sites listed in "Instructions followed" Below which should have
installed the above missing packages.
Unsure if the Error "$(lsb_release Release' does not have a Release file." was
the cause of an unusable trace file, I ran ~$ find-dbgsym-packages
[core_path|running_pid|binary_path]
. . .and received "I: All needed dbgsym packages are already installed."
I clicked [Reload] in the "Crash Reporting Assistant of the Kde Crash Handler"
and still received
"The generated crash information is not useful"
and the same list of missing packages.
I backed up in the assistant to the first step and found the automated process
UN-enabled and the following report

I am missing something, as these conflicting messages are confusing and me
unsure what is causing which.
Any way I can help to clarify this, please ask.

ADDITIONAL INFORMATION
[1] In https://ubuntu.com/server/docs/service-debuginfod I was
advised, " If you use Bash, you can do that by adding the following snippet to
your ~/.bashrc:
export DEBUGINFOD_URLS="https://debuginfod.ubuntu.com";
but neither Files or Dolphin can show any [.] files in [/] or a ".bashrc:" in
Home where [.] files are shown.
As this is a 22.04 version is such an addition even necessary I wonder?
