Is there any alternative to Ibus typing booster for Ubuntu 18.04. I am not able to install ibus typing booster in Ubuntu 18.04. I have tried the solutions provided in askubuntu forum.
ibus-typing-booster is available in the official repositories since Ubuntu 20.04. Unfortunately, it is not available as .deb package for releases of Debian or Ubuntu prior to 20.04.
That means you will need to compile it yourself. Here are some brief instructions (source):
sudo apt-get install ibus libibus-1.0-dev git clone git://github.com/mike-fabian/ibus-typing-booster.git cd ibus-typing-booster ./autogen.sh ./configure --prefix=/usr --libexecdir=/usr/lib/ibus make sudo make install
The official manual is available here.
