https://github.com/termux/termux-packages/pull/25962 is just merged. But for that, you must install termux from f-droid and termux-x11-nightly.apk from GitHub and a windows manager like xfce on your phone etc etc. This is why I describe it as theoretically.

Here's the explanation for why the wiki (and others) are currently down:

Unfortunately code.gnucash.org http://code.gnucash.org/, which provides these mailing lists, the wiki, the bug tracker, nightly builds, and some other services, has been hammered the last several days by bots scraping the wiki and bug tracker resulting in connection timeouts for everything. In order to reduce the impact Derek and I decided to disable access to the wiki and bug tracker. They’d been rendered useless anyway so weren’t doing anybody any good and this allows the rest of the services to work normally.
