Po přihlášení na Ubuntu přes Putty/SSH, se můžeme při spouštění některých programů (využívajících termcap/curses) setkat s chybovým hlášením „Unknown terminal: putty-256color„.

root@svoci1:/root# mc Unknown terminal: putty-256color Check the TERM environment variable. Also make sure that the terminal is defined in the terminfo database. Alternatively, set the TERMCAP environment variable to the desired termcap entry. |
Jednoduchým, rychlým, ale pouze dočasným řešením je nastavení proměnné TERM na hodnoty např. xterm, vt100 nebo screen.
Trvalým vyřešením je instalace balíčku ncurses-term.
