[regression] RadioTray won't launch without python-xdg & gir1.2-appindicator3-0.1

When you run radiotray from the command line, you get the following error:

user@pc:~$ radiotray
/usr/lib/python2.7/dist-packages/radiotray/XmlDataProvider.py:23: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gtk
Traceback (most recent call last):
  File "/usr/bin/radiotray", line 12, in <module>
    os.chdir(workdir)
OSError: [Errno 2] No such file or directory: '/usr/bin/src'

Status changed to 'Confirmed' because the bug affects multiple users.

Eugene San wrote to me:

I am using Ubuntu 16.04 and today installed the app from official repository and it started and working without any issues.

From details in bug report I see a couple of harmless warnings and an error.
The error might be due to the leftovers of an old instances of the app in your system or user profile.

Also you might want to purge and then reinstall the packages (this shouldn't affect your personal stations list):
1. dpkg --purge radiotray
2. Check ~/bin, /usr/bin, /usr/local/bin, /usr/share/, /usr/share/applications and /usr/lib/python2.7/dist-packages/ directories for radiotray related files and remove them
3 apt-get install radiotray

In case above doesn't help, please attach "radiotray.list" file generated by the following commands, after performing step 1 above:
$ find / -name "*radiotray*" > radiotray.list
$ which radiotray >> radiotray.list
$ echo $PATH >> radiotray.list

I tried the following commands to fix radiotray, but it is still broken:

sudo apt-get remove radiotray ; sudo rm -rf ~/.local/share/radiotray /usr/share/app-install/icons/radiotray.png /usr/share/app-install/desktop/radiotray:radiotray.desktop /var/cache/apt/archives/radiotray_0.7.3-5ubuntu1_all.deb ; sudo apt-get install radiotray

Here's the output of find / -name "*radiotray*"

Fresh install on latest Xenial Version:

Manual Start gives this error:
pizzard@pizzard-PC:~$ radiotray

I guess the reason for that behavior is that in Xenial the package 'python-xdg' is not present by default.
Perhaps because in Xenial there is 'just' Python3 available per default?

The solution on my side is to install the package 'python-xdg'.
Then radiotray launches and works as expected.

So the global solution could be to change the program in order that 'python-xdg' is made available?!

That's just my two cents.

Enjoy Ubuntu and enjoy radiotray :-).

Thanks Axel, install 'python-xdg' fix this bug for me too.

Thanks !

I too confirm that this fixed the issue:
sudo apt-get install python-xdg

So, it seems that if someone can add python-xdg as a dependency during (sudo apt-get install radiotray), the problem will be completely fixed for *everyone* who installs radiotray.

I have python-xdg installed but I'm still getting the same error so it's not a a forgone conclusion that installing python-xdg as a dependency of radiotray will fix the issue;

I have to point out that the error message you have differs from the one I got and for me installing python-xdg fixed to problem.
So I suppose you miss another dependeny package we did.

python-xdg is still a necessary dependency, it just may not be sufficient in your case.

Hi Martin, how can I find out what other dependency is missing?

When I run radiotray from the terminal I get the same output as you. The icon loads in the systray and it works fine for me.

I get a black icon in the tray and left or right clicking does nothing;

http://imgur.com/vr3JtDa

I just did a fresh install of Ubuntu 16.04 (for other reasons). Again, radio tray would not launch, but (again) it launched fine after this:
sudo apt-get install python-xdg

Screenshot:
http://neartalk.com/ss/2016-04-24_001_1121x888.png

I can't understand why you're getting that black icon. Are you using the Unity desktop?

Here my two cents, inspired by the Debian bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=801232 which is not necessarily the same thing but mentions a nice debug command: "from radiotray import radiotray_runner" (see below)

[HACK] So the hack is clearly installing apt-get install python-xdg
[SOLUTION] The solution is adding python-xdg to Depends

[CROSS-LINK] Btw the bug is very similar to Bug 55179

I have two machines: one was upgraded from wily to xenial, there the problem didn't appear as the package was already installed. Only on a fresh xenial installation the problem appeared. My flavour is Xubuntu, it's possible that Ubuntu flavour already contains the missing package.

Correction:

The bug is NOT very similar to Bug 55179, it is very similar to Question 55179 (it's confusing that a bug and a question with the same ID can exist...)

Damn. Live is not easy, and an edit button doesn't exist on launchpad. Here is the Link: https://answers.launchpad.net/gwibber/+question/55179 (Question 55179)

Same issue as above; I installed python-xdg, which gets radiotray further, but I don't get an icon in the notification area.

maybe check that gir1.2-appindicator3.01 is installed too

Fresh Install of « Kubuntu 16.04 »
* Same bug
* Install python-xdg
* radiotray start, but black not usable icon
* install gir1.2-appindicator3.01
* radiotray start, and fully working.

Need add depends to « python-xdg and gir1.2-appindicator3.01 »

gir1.2-appindicator3-0.1 is the correct name for the package gir1.2-appindicator3.01. On my system, it was already installed

New 16.04 install. Ogg-streams used to play fine in 14.04

@Stephen

I have tested your both links above with a gnome-shell session 64 bits:
- works as expected: each 3 minutes song is played, a short silence, then the next song is played
- my system have these libs installed: libogg0 & libshout3

I recently had an issue with the radiotray load (maybe due to some broken installation links); so i've purged (sudo apt-get purge radiotray) and then reinstalled it. Since it play as expected.

Thanks for your quick work on my problem, dino99.

I, too, have libogg0 & libshout3 installed (on a 32-bit system). I purged and re-installed radiotray, as suggested, but my ogg streams are still halting.

I notice that the ap doesn't shut down smoothly either: the radiotray icon disappears from the top panel leaving a momentary "hole". I think I'm still a package missing. When I re-installed radiotray, apt put-up these "suggestions".

python-dbus-doc python-dbus-dbg python-gi-cairo python-gtk2-doc
python-genshi python-lxml-dbg python-lxml-doc

would any of them do any good?

There is a (pretty incomprehensible to me) radiotray log, and I suppose I could run it "verbose" mode from a terminal. Would that help?

Of course, there is a simple workaround - just listen to mp3 streams. But the sound quality is not as good.

HELP!, HELP!, HELP!

(me again) I ran ran RT from a terminal, and got this:

It seems to me that some files need editing here, but what do I edit and how?

Advice from the grey-beards of Ubuntuland very gratefully received

@Stephen

dont worry, its only warnings due to some new libs now used on the system, but still not updated inside radiotray (so those scary messages, but they are harmless). Hopes someone will rebuild radiotray and drop it into a ppa soon.

If you get real problem, then watch logs to find something related & usefull

Thanks for the quick (and reassuring) reply, 9d9

I don't understand why this bug is still not fixed. The fix is simple: just make python-xdg a radiotray dependency, so that, when you install radiotray, it also installs python-xdg automatically. Done!

That now means it is an ubuntu packaging issue (as debian maintainer suggests)

This bug is still valid:
I just installed radiotray on a clean 16.04 install
Radiotray was not launching and installing python-xdg manually fixed it

0.7.3 is still broken - unfortunately radiotray is not under active development so no migration path is available :-(

At least yakkety got some updates:

radiotray (0.7.3-6ubuntu1) yakkety; urgency=low

  * Merge from Debian unstable. Remaining changes:
    - debian/patches/use-appindicators.patch: Patch config to use appindicator
      by default.
    - debian/control: Depend on python-appindicator.

Only works for me (without an icon but just an empty space in tray) on plasma 5 after installing these packages:
gir1.2-appindicator3-0.1 gir1.2-appindicator-0.1 libappindicator1 libappindicator3-1 python-appindicator

Works for me again after installing python-xdg as suggested by Axel above.

changed settings see attachments
gksudo xed ~/.local/share/radiotray/config.xml

activate systray as a helper application

installing python-xdg fixed this for me as well

In my case, same error about `usr/bin/src`
radiotray stopped working after I set python3 as default. running it with `python2 /usr/bin/radiotray` gets it working.
So I digged a little bit, found out that radiotray is installed under `/usr/lib/python2.7/dist-packages/radiotray`, so I guess radiotray has to be ported to python3 with some modifications.

My solution for the problem is to modify `/usr/bin/radiotray` change its first line to `#!/usr/bin/python2`
