Hi again.
Did Nik mean chmod o+w or chmod a+w? I looked to the manpage, a+w is writeable for everyone. It can solve the message "failed to open '/etc/tqt3/tqt_plugins_3.5rc.tmp'". But I learned that user shouldnt write in /etc/... folder.
When I made chmod a+w /etc/tqt3 does it affect on /etc or only in /etc/tqt3? I dont want to destroy my system. :/
For the new readers, this is my problem:
I have ubuntu 18.4 with trinity R14.0.5. If I want to start the arduino ide from arduino.cc (download and extract arduino-1.8.7-linux64.tar.xz) there comes the splash-screen for one second and it crashes with this message:
~/arduino-1.8.7$ ./arduino Picked up JAVA_TOOL_OPTIONS: TQSettings::sync: failed to open '/etc/tqt3/tqt_plugins_3.5rc.tmp' for writing
What I have to install or change?
I logged in today with the ubuntu standard desktop and the arduino ide works great.
deloptes points in devel to $CLASSPATH, the var in empty in my shell. ./arduino is a bash script.
Thanks for the help.

Hi!
I have 14.0.6~pre + openjdk-8-jre-headless + arduino 1.8.3. I remember that I once saw the error you described, but that's been quite a while. You might try "chown a+w " as a last resort :-/
but this has nothing to do with OPs problem and it is a bad idea to give permission to everybody to write in /etc (you mean chmod o+w).

Because it pissed me I downloaded the tool and ran the install script. After this I typed ./arduino and the gui started.
Looking into the install script it might be that it creates links in your current environment, so I sugggest 1. login in default ubuntu 2. run uninstall.sh 3. login in TDE 4. run install.sh 5. ./arduino 6. it should work

Hi,
Thanks for the help. The error is the same:
TQSettings::sync: failed to open '/etc/tqt3/tqt_plugins_3.5rc.tmp' for writing
Strange thing, I use arduino since many years. It works always without the install.sh script.
I solved the problem with 'sudo chmod a+w /etc/tqt3', it starts. But I am not happy with it.
Best regards

Sure that is not the best solution, but it get's things done. I remember that I had this problem quite some time ago. It was solved in later versions of TDE, so you might want to use the Slavecs "bleeding edge" repository.
Maybe this could also work - leaves just one file for your user r/w in /etc/tqt3:
$ touch /etc/tqt3/tqt_plugins_3.5rc.tmp $ sudo chmod 0755 /etc/tqt3 $ arduino

Interesting. Which version of TDE is installed?
Hi again Nik,
I have R14.0.5 the latest stable. Is it possible to install the latest unstable to test and switch back after that? I am afraid that config files will become unusable for the stable as result.

I would be quite surprised if any config file changes in a incompatible way - but I have never moved back to stable. To be sure copy your ~/.trinity to ~/_trinity-save.

Hi Nik,
I didn't test it, it's too dangerous. I am using Arduino in a VM since then :/.

Hi MLR,
the problem with start arduino ide is definitely not caused by writing to /etc/tqt3/tqt_plugins_3.5rc.tmp. This message only diverts attention from the real problem. Please do:
1. apt-get purge kgtk-qt3-trinity 2. log out from TDE 3. log in again to TDE 4. try to run arduino ide
Cheers
Hello Slávek,
the package kgtk-qt3-trinity is not installed.
Have a nice day

Hi MLR,
well, if kgtk-qt3-trinity is not installed, here is another potential source of problems: gtk-qt-engine-trinity and gtk3-tqt-engine-trinity. In Trinity Control Center, check the GTK engine setting and set it to another engine, than QT-Engine and TQT-Engine.
Cheers

where in trinity control center is this located? i ask not because of the original poster's problem but for another issue: after having worked for years, my flatbed scanner, using epson's iscan software, doesn't work anymore. starting it from a terminal to catch the errors, i get this:
[kcrash] TDECrash: Application 'iscan-gtk-tqt-application' crashing...
the backtrace renders this:
iscan-gtk-tqt-application: No such file or directory.
as well as pages of other things about the machine and what's installed. i've never heard of iscan-gtk-tqt-application before.

Hi Dep
Try grabbing the firmware binary from the windows drivers and have it load when you call the scanner.
You will have to check out some howtos to get it right. This is assuming it's a firmware loading problem like mine was.
Find the conf file for your scanner and add something like
# Path to the firmware file # This file comes with the Windows driver # The scanner won't work without it option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
Userful Sites: https://everythinglinux.org/scanner/index.html http://manpages.ubuntu.com/manpages/trusty/man5/sane-epson2.5.html http://ljm.home.xs4all.nl/SANE-faq.html

Thanks very much -- I'll do this if I can't get the native software to work. What puzzles me about it is that the Epson-provided Linux IScan application has always worked reliably here, and only now when I invoke it does it explode.

Hi, can you please not hijack others threads?!
Which iscan version are you using? I had to patch iscan-2.30.3 in order to work on stretch. I can post you a link to the package(s)

inasmuch as there was a tqt issue in the original post, i had no reason to suppose that this was not pertinent to the original discussion. but thanks anyway for the scolding, which like java you seem to do on many platforms.<g>
