Question: I am trying to build a program on Linux. The development release of the program comes with "autogen.sh" script. When I run it to create configure script, however, I am getting the following error:
Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 326.
autoreconf: failed to run aclocal: No such file or directory

How can I fix this problem?

sudo apt-get install automake

this is what happened after i update the system
