Can't click on link in About

Clicking on your website link causes Operation not supported. Viewnior 1.6

[manungsa]

After searching for some time, I found some old website and forum with (I think) related problem, so basically you need to install gvfs package. Do you have installed it? If it has been installed, I don't know more (I'm not pro at this).

Well that is marvelous... One has to install a new big architecture, just to make a hyperlink work. What will they think up next. https://gitlab.gnome.org/Infrastructure/Infrastructure/-/issues/1016 https://en.wikipedia.org/wiki/Talk:GVfs

[manungsa]

Does installing gvfs solved your problem? Just to make sure.

[ncmprhnsbl]

fwiw, with 1.7 on arch, it works without gvfs. just guessing, but this sort of thing generally/often uses xdg-open, part of the xdg-utils package. see also: xdg-settings and xdg-mime.. ...maybe

All I know is in Debian Sid,

Package: viewnior
Version: 1.6-1+b3
Versions of packages viewnior depends on:
ii  libc6                2.36-8
ii  libexiv2-27          0.27.6-1
ii  libgcc-s1            12.2.0-14
ii  libgdk-pixbuf-2.0-0  2.42.10+dfsg-1+b1
ii  libglib2.0-0         2.74.6-1
ii  libgtk2.0-0          2.24.33-2
ii  libstdc++6           12.2.0-14
viewnior recommends no packages.
viewnior suggests no packages.

I really am not in the mood to add new filesystem stuff to my computer to test this out.

[jidanni]

$ aptitude search ~i~nxdg
i   xdg-utils

So that's the only xdg package I have installed. Anyway, perhaps the Debian viewnior package is missing a dependency.

[ncmprhnsbl]

yes, they're all in the xdg-utils package suggestions: $ xdg-settings --list

$ xdg-settings get default-web-browser

$ xdg-settings set default-web-browser (some web browser).desktop

$man xdg-settings (for more)

[jidanni]

$ xdg-settings --list
Known properties:
  default-url-scheme-handler    Default handler for URL scheme
  default-web-browser           Default web browser
$ xdg-settings get default-web-browser
firefox.desktop
$ firefox --version
Mozilla Firefox 111.0.1

What am I doing wrong?

[ncmprhnsbl]

looks like the xdg thing isn't it. on another setup(void) also without gvfs, it seems to favour x-scheme-handler/http=(some-browser.desktop) set in /usr/share/applications/mimeinfo.cache (update-desktop-database generates this) looking at viewnior source suggests that the whole 'about' dialog relies on internal gtk stuff to handle this, so a question might be: does the about dialog in other gtk apps work correctly for you? unless something's changed in viewnior regarding this between 1.6 and 1.8..

[jidanni]

OK, I found some other GTK packages on my system,

set viewnior
aptitude show $@|grep --color gtk
set libgtk2.0-0
aptitude -s purge $@

And indeed,

Gee, so many "//" !

[jidanni]

OK, I updated it to

x-scheme-handler/https=google-chrome-unstable.desktop
x-scheme-handler/http=google-chrome-unstable.desktop

And... it works. So I'll close this bug.

But I would just like to comment,

that 
      this
           whole
                  thing
takes
       several
               Ph. D's
                     to debug,
because,
            well,
                 whatever is to blame also takes many Ph. D's to figure out.

[jidanni]

Can someone do me a favor?

Can someone report a bug to the parties who create the "Could not show link Operation not supported" message seen on many programs.

And tell them to add some words saying why.

They could say "check your mimetypes files, Gramps" or something.

At least then we would have a more precise search string to Google with to find other people in the same predicament.

Never mind, I'll just put it into https://unix.stackexchange.com/questions/742104/how-to-fix-could-not-show-link-operation-not-supported
