I don't understand this comment.

Indeed, I can have only one of these at the time.

Sounds good to me. But I don't understand much about GUI
programming... :/

Yes, sorry for the confusion.

Yes, they are all architecture "all", so there is no action required.

I was struggling with this as well, and that led to my initial bug
report. As I wrote, trying to co-install these, and other relevant,
packages is quite a bit of a hit-and-miss experience. I think this
should be a limitation in apt and aptitude. What I did to co-install
these packages, was to actually download the packages individually, then
installing them like this:

# dpkg -i pkg1 pkg2 pkg3 ...

Please note that this is neither an acceptable solution for the average
end user, nor is it straightforward: You have to co-install all relevant
packages in one go, otherwise, you'll end up with eg. only the i386
versions of it, or whichever version you specified last.

As things currently stand, it looks like these packages are
co-installable, just not via apt or aptitude.

libjasper1 1.900.1-14 is in unstable, not in testing.

Maybe I have a problem there, with libcolord1...

Yes. I've written a script to download packages at specific versions to have
the same versions for both architectures. Otherwise, if the versions differ,
dpkg refuses to install anything. But I had to use --force-overwrite plenty
of times, anyway.

That would be great!

I am currently running fcitx, but this has problems of its own, most
notably (in my experience, anyway - I guess it works better elsewhere):
It's impossible to activate and deactivate it using Super_R (one of my
only unused keys not already captivated by other applications), keyboard
shortcuts are hard to configure, and the popup menu that indicates the
current settings, and the preview window that offers the choices, is so
tiny that it is very hard to read for me (oh, and I cannot scroll the
list of choices, too). @Aron: Should I file bugs for any of these?


Kind regards,
