1. linux 환경에서 texlive (2019.20200218-1) 를 설치한 후에 tlmgr 명령을 실행하면 항상 아래의 글자가 뜨고 translations 패키지 들어가 보면 한글은 없습니다. 어떻게 해야죠?

Sorry, no translations available for ko_KR (nor ko); falling back to English.
Make sure that you have the package "texlive-msg-translations" installed.
(If you'd like to help translate the installer's messages, please see
http://tug.org/texlive/doc.html#install-tl-xlate for information.)

2. tlmgr 로 Ktug repository 추가해주고  tlmgr repository status 으로 확인해보면 pubkey missing 상태로 나오는데 어떻게 verify 해야하나요?

tlmgr: package repositories
main = https://ctan.math.illinois.edu/systems/texlive/tlnet (verified)
ktug = http://ftp.ktug.org/KTUG/texlive/tlnet (not verified: pubkey missing)
For more about verification, see .
ktug http://ftp.ktug.org/KTUG/texlive/tlnet/tlpkg/texlive.tlpdb pubkey missing
main https://ctan.math.illinois.edu/systems/texlive/tlnet/tlpkg/texlive.tlpdb verified
