libcurl.so.4 problem

Hi All, while updating I'm blocked in one of my computers not being able to update clang, llvm, and perhaps other packages. This is what I get; cmake: error while loading shared libraries: /usr/lib/libcurl.so.4: file too short. Googling I found many suggestions, but no one worked for me. This is my locate libcurl.so.4 output:    /usr/lib/libcurl.so.4    /usr/lib/libcurl.so.4.5.0    /usr/lib/libreoffice/program/libcurl.so.4. I changed the localedef from    localedef -i it_IT -f UTF-8 it_IT.UTF-8    to:    localedef -i it_IT -f ISO-8859-1 it_IT     and viceversa but nothing changes. I would be very obliged if someone of our experts would explain me what I should do. Thanks Giorgio Cittadini
