Ulauncher

AmsterDan

Hi all. I would like to use Ulauncher and run into the problem of the app not starting in the first place. I may have to take this to the developers or Github, but perhaps it's an easy fix.

Solus 4.4
Budgie version:10.8.1
Windowing: X11

Installed Ulauncher:
sudo eopkg install ulauncher
Rebooted computer.
'Ctrl + Space Bar' should run the application. Doesn't work.
Attempted to run from the menu. Doesn't work.
Attempted to run in terminal:

x@x ~ $ ulauncher Traceback (most recent call last): File "/usr/bin/ulauncher", line 27, in <module> from ulauncher.main import main File "/usr/lib/python3.10/site-packages/ulauncher/main.py", line 25, in <module> from ulauncher.ui.windows.UlauncherWindow import UlauncherWindow File "/usr/lib/python3.10/site-packages/ulauncher/ui/windows/UlauncherWindow.py", line 41, in <module> from ulauncher.ui.windows.PreferencesUlauncherDialog import PreferencesUlauncherDialog File "/usr/lib/python3.10/site-packages/ulauncher/ui/windows/PreferencesUlauncherDialog.py", line 14, in <module> gi.require_version('WebKit2', '4.0') File "/usr/lib/python3.10/site-packages/gi/__init__.py", line 129, in require_version raise ValueError('Namespace %s not available for version %s' % ValueError: Namespace WebKit2 not available for version 4.0

Where to go from here?

AmsterDan Install libwebkit-gtk and try again.

@algent I am one happy camper in Linuxville again! Thanks. This is the first time that I have started using a Linux distro full-time and plan on taking an active approach to solving problems myself. Slowly learning more about the system and how it works.

In this case, I was aware of that last line, the ValueError with WebKit2 not availble for version 4.0. In other words, make it available. I would have never guessed to try search for 'libwebkit-gtk'.

My noob self would try:
x@x ~ $ sudo eopkg search webkit libwebkit-gtk41-dbginfo - Debug symbols for libwebkit-gtk41 kdewebkit-devel - Development files for kdewebkit gnome-web - GNOME web browser based on the WebKit rendering engine. gnome-web-dbginfo - Debug symbols for gnome-web libwebkit-gtk5 - Web rendering engine kdewebkit-dbginfo - Debug symbols for kdewebkit wkhtmltopdf-devel - Development files for wkhtmltopdf libwebkit-gtk-dbginfo - Debug symbols for libwebkit-gtk libwpe - General-purpose library specifically developed for the WPE-flavored port of WebKit. qt5-webkit-dbginfo - Debug symbols for qt5-webkit libwpe-devel - Development files for libwpe webvfx-devel - Development files for webvfx libwebkit-gtk41 - Web rendering engine libwebkit-gtk41-devel - Development files for libwebkit-gtk41 libwebkit-gtk-devel - Development files for libwebkit-gtk perl-glib-object-introspection - Glib::Object::Introspection - Dynamically create Perl language bindings perl-glib-object-introspection-dbginfo - Debug symbols for perl-glib-object-introspection libwpe-dbginfo - Debug symbols for libwpe qt5-webkit-devel - Development files for qt5-webkit libwebkit-gtk5-devel - Development files for libwebkit-gtk5 wpebackend-fdo-dbginfo - Debug symbols for wpebackend-fdo libwebkit-gtk5-dbginfo - Debug symbols for libwebkit-gtk5 kdewebkit - Integration of the HTML rendering engine WebKit wpebackend-fdo - FreeDesktop backend for WPE WebKit wkhtmltopdf-dbginfo - Debug symbols for wkhtmltopdf libwebkit-gtk - Web rendering engine wkhtmltopdf - HTML to PDF converter qt5-webkit - Qt5 support for Webkit wpebackend-fdo-devel - Development files for wpebackend-fdo

Since the suggestion was to make 'webkit2' available, I'd be looking at some webkit '2', which is not in the list. And then I'd be wondering if the 'libwebkit' is different from just 'webkit'. I guess it comes down to 'just knowing' these things? Or is there an actual way to explain that to me? What for example, does the 'lib' mean in 'libwebkit'?

Anyhow, just trying to apply some form of sense to it for my own understanding. Thanks again!

AmsterDan What for example, does the 'lib' mean in 'libwebkit'?

lib because it contains libraries,
https://github.com/getsolus/packages/blob/main/packages/l/libwebkit-gtk/pspec_x86_64.xml#L28C58-L28C58

It was easy to find for me because this package already was installed on my system. I searched for webkit2 and 4.0 and found that these files are part of libwebkit-gtk package.
