I recently started having problems with running programs like sqlite3 or awk on Ubuntu20. These programs won't start and just show this error: symbol lookup error: /usr/local/lib/libreadline.so.8: undefined symbol: UP

I found several solutions but those usually lead to installing libreadline from source. I removed libreadline and libhistory and their symlinks from /usr/local and followed this guide: https://noknow.info/it/os/install_readline_from_source

I installed it, made all symlinks, updated ENV variables but the problem still persists.

These solutions (https://stackoverflow.com/questions/26670417/how-to-compile-readline-from-source and https://stackoverflow.com/questions/46881581/libreadline-so-7-undefined-symbol-up ) suggest that invalid symbol may be defined here /usr/lib/libncurses.so but tsuch file is not in my system.

Please let me know if you have any suggestions what I can do to fix this problem.

  • Maybe it's in a different location now; the question you referenced is 6+ years old. On my Mint 20 system, it's in `/usr/lib/x86_64-linux-gnu`. – ajgringo619 Apr 07 '21 at 22:14
  • The installation guide worked when ./configure had been run with --enable-shared option.(```./configure --prefix=/usr/local/readline/8_0 --enable-shared```) – Juraj Bezručka Apr 08 '21 at 09:12
  • I removed my locally installed libreadline.so from the $HOME/.local/lib folder and it awk started to work. – Dipanker Singh Jul 04 '23 at 02:29
  • https://noknow.info/it/os/install_readline_from_source now redirects to an entirely useless website – mcmuffin6o Aug 22 '23 at 23:43
