In the case of Debian templates, I had been installing software solely through templates, but for the input methods, I ended up installing, removing, and reconfiguring both fcitx and ibus in a messy manner. If I find myself in this situation, would I have no choice but to create a new Debian template or reinstall Qubes OS from scratch?
I tried various things, but even in the untrusted template, I couldn’t get it to work at this stage, and the Hankaku/Zenkaku key would only produce the " ’ " character. I had installed fcitx in the template (there were articles suggesting to use --install-recommends, but…), and now I’m considering configuring fcitx only in the untrusted template.
