[Bug 1598157] [NEW] WebApp crashes with Ubuntu 16.04 (modules not installed, Uncaught ReferenceError)

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

1) The release of Ubuntu I am using, via 'lsb_release -rd'

$ lsb_release -rd
Description:	Ubuntu 16.04 LTS
Release:	16.04

2) the package I am using via 'apt-cache policy pkgname'

$ apt-cache policy unity-webapps-twitter
unity-webapps-twitter:
  Installed: 2.4.16+16.04.20151119-0ubuntu1
  Candidate: 2.4.16+16.04.20151119-0ubuntu1
  Version table:
 *** 2.4.16+16.04.20151119-0ubuntu1 500
        500 http://de.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages
        500 http://de.archive.ubuntu.com/ubuntu xenial/universe i386 Packages
        100 /var/lib/dpkg/status

3) What I expected to happen

I have been using the WebApp with Ubuntu 14.04 for the last years. Now I
am migrating to Ubuntu 16.04 and I expected to run WebApp for Twitter as
I used to with Ubuntu 14.04.3

I usually execute /usr/share/applications/Twitter.desktop

[Desktop Entry]
Name=Twitter
Type=Application
Icon=unity-webapps-twitter
MimeType=
Actions=S0;S1;S2;S3;S4;S5;S6;S7;S8;S9;S10;
Exec=unity-webapps-runner -n 'VHdpdHRlcg==' -d 'twitter.com' %u
StartupWMClass=Twittertwittercom


4) What happened instead

I found the WebApp unfeasible. This is the result of executing “unity-
webapps-runner -n 'VHdpdHRlcg==' -d 'twitter.com' %u” in a GNOME
terminal

user@box3:~$ unity-webapps-runner -n 'VHdpdHRlcg==' -d 'twitter.com' %u
