I need to install Tesseract, that need to install autoconf automake libtool, However I got the error as follows:
sahu@sahu-desktop:/$ sudo apt-get install autoconf Reading package lists... Done Building dependency tree Reading state information... Done Package autoconf is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'autoconf' has no installation candidate
So please help me.
