this is what I did in Lubuntu 22.04:
``` sudo apt install build-essential sudo apt install libgtk-3-dev ```
(Note: change the expression USERFILE to user name)
in /home/USERFILE I created the file `geany_build`
then I downloaded the nightly tarball from https://download.geany.org/geany_git.tar.gz then I untared the nightly tarball called `geany_git.tar.gz`; then I copied the content of the untared geany_git in the file `geany_build`
in the terminal I went into the content of geany_build by the command `cd geany_build`
then I did this: `./configure --prefix=/home/USERFILE/geany_build --disable-html-docs` the answer is: `bash: ./configure: No such file or directory`
