Bug ID: 376548
Summary: discover cannot connect to internet for update
packages, crashes if a package "removal" is requested
and denied
Product: Discover
Version: 5.8.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: mwinth...@comcast.net
Target Milestone: ---
Application: plasma-discover (5.8.5)
Qt Version: 5.6.1
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-62-lowlatency x86_64
Distribution: Ubuntu 16.04.2 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Performing update per tray icon notification
- Unusual behavior I noticed:
discover reported it would remove some kxstudio package items. It offered the
choice to "remove" them or not. I selected "not" and discover crashed. Usually
discover will ask for "permissions" to install, and this is the first time it
asked first to "remove". It got no further. When discover asks for permissions,
it always fails because it claims the "internet is not available" (WiFi). I
intend to string an rj45 wire connectionto the internet and see if it still
fails. This bug report is using the WiFi connection that discover can never
use.
- Custom settings of the application:
Since installation, discover has never been able to install the updates it
identifies. It locates the updates, asks for sudo authority, and then reports
that is cannot find the internet connection (WiFi). This is absurd because it
found the updates via internet before it asked to install them. I have been
using "sudo apt-get update; sudo apt-get upgrade" in a terminal window since
discover showed this behaviour.
Today, after the crash, I decided to see if there was a problem with
permissions:
root@dad314159:/home/dad/Desktop# ps -elf | grep iscover
0 S dad 4866 3803 1 80 0 - 337382 poll_s 08:43 ? 00:00:07
/usr/bin/plasma-discover --mode update
0 S root 5718 4963 0 80 0 - 3220 pipe_w 08:51 pts/0 00:00:00 grep
--color=auto iscover
root@dad314159:/home/dad/Desktop# ls -l /usr/bin/plasma-discover
-rwxr-xr-x 1 root root 946520 Dec 29 14:08 /usr/bin/plasma-discover
root@dad314159:/home/dad/Desktop# sudo chmod 777 /usr/bin/plasma-discover
I then ran discover again, and it did not crash, and instead closed when I
demurred about the kxstudio removals.
I repeat, discover has never been able to connect to the internet for updates.
I have tried ubuntu software center and had success on some occasions and
"failure to connect" on other occasions. synaptic always is successful. asp-get
always works.
The crash can be reproduced sometimes.
