@Gunnar Hjalmarsson: Thank you for your help and your patience! Finally, I succeeded!
I don't know which steps help to resolve this problem, and just list what I have done: 1. Removed mn_MN and mn_MN.utf8; 2. Run "sudo vim /etc/locale.gen", and uncomment all lines starting with zh_CN, and run "sudo locale-gen"; 3. As you instructed, I chose "none" as the Keyboard input method system, and then run "rm ~/.cache/ibus/libpinyin/*", and then reboot. 4. Then I imported a data file used in Ubuntu 18.04 and tested a phrase, which works; 5. Then I try to export, and find it works. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus-libpinyin in Ubuntu. https://bugs.launchpad.net/bugs/1893736 Title: ibus-libpinyin can not export user phrases Status in ibus-libpinyin: New Status in ibus-libpinyin package in Ubuntu: Invalid Bug description: System: Ubuntu 20.04; English is the default language; ibus-libpinyin is installed by adding input sources through settings. After enabling "Remember every input as a phrase" option, ibus- libpinyin is supposed to be able to import and export user phrases. However, although the export button works, it exports to a blank document (the exported file type I used is txt). I also tried to import a pinyin data file I used on Ubuntu 18.04 first, and then export, but I still got a blank document. I have checked that dependencies on https://github.com/libpinyin/ibus-libpinyin/wiki/Installation#ibus-libpinyin-dependencies are all satisfied except that libpinyin13 is on my system instead on libpinyin.can not export user phrases.
