How to fix "/usr/local/lib/libldap_r-2.4.so.2: no version information available" error
When I ran "sudo apt update" this morning these errors showed up: /usr/lib/apt/methods/https: /usr/local/lib/libldap_r-2.4.so.2: no version information available (required by /usr/lib/x86_64-linux-gnu/libcurl-gnutls.s o.4) /usr/lib/apt/methods/https: /usr/local/lib/liblber-2.4.so.2: no version information available (required by /usr/lib/x86_64-linux-gnu/libcurl-gnutls.so. 4) This error means libcurl was compiled with a version of libldap_r other than what I have in /usr/local/lib. So a work around is to symlink the missing files: sudo ln -fs /usr/lib/liblber-2.4.so.2 /usr/local/lib/ sudo ln -fs /usr/lib/libldap_r-2.4.so.2 /usr/local/lib/
