libtinfo6을 설치할 수 없습니다

iraf를 설치하려고 하는데 다음 오류가 발생합니다. 어떻게 해결하나요?

sudo apt install gcc make bison flex libncurses-dev tcl-dev

Note, selecting 'libncurses5-dev' instead of 'libncurses-dev'
bison is already the newest version (2:3.0.4.dfsg-1build1).
flex is already the newest version (2.6.4-6).
make is already the newest version (4.1-9.1ubuntu1).
tcl-dev is already the newest version (8.6.0+9).
gcc is already the newest version (4:7.4.0-1ubuntu2.3).
libncurses5-dev is already the newest version (6.1-1ubuntu1.18.04).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 xgterm : Depends: libtinfo6 (>= 6) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify fy a solution).

나는 다음과 같이 글을 써 보았습니다.

apt --fix-broken install 

일부 옵션만 제공합니다.

저는 리눅스 민트 19.2를 사용하고 있습니다. xgterm을 작성하면 다음과 같은 결과가 나옵니다.

xgterm: error while loading shared libraries: libtinfo.so.6: cannot open shared object file: No such file or directory
