Error

The error libtinfo.so.6: no version information available typically occurs because the ncurses package provided by the default Conda channel lacks symbol versioning, which system binaries (like bash or samtools) expect.

Check and Fix

根據 StackOverflow 上的建議，我需要升級 conda-forge 的 ncursesw

micromamba install -c conda-forge ncurses

但還是會報警。對比發現是安裝的版本來自 anaconda channel，而非conda-forge

micromamba list ncurses

  Name     Version  Build       Channel 
──────────────────────────────────────────
  ncurses  6.5      h7934f7d_0  anaconda

原來是兩個 channel 同時存在相同版本，在沒有設定channel priority的情況下可能優先安排了 anaconda 的版本。

為了確保安裝到 conda-forge 版本，還需要指定版本和 build 進行安裝

micromamba search ncurses
micromamba install -c conda-forge ncurses=6.4=hcb278e6_0
# micromamba install -c conda-forge ncurses=6.4=hcb278e6_0 --force-reinstall

Done

remove channcels: defaults

micromamba config append channels conda-forge
micromamba config set channel_priority strict
