Freemind is a cross-platform, GPL-based free software that is written in Java and is a software for drawing mind maps. The resulting file format suffix is. mm. Can be used to make notes, brain chart records, brain stress soup, etc.
Ubuntu only needs to be entered in the terminal
$ sudo apt-get install Freemind
Can be installed if an error similar to the following appears:
Checking Java Version ...
| Java.io.FileNotFoundException:/home/xx/.freemind/auto.properties (No such file or directory)
| At Java.io.FileInputStream.open (Native Method)
| At Java.io.fileinputstream.<init> (fileinputstream.java:137)
| At Freemind.main.FreeMindStarter.readUsersPreferences (freemindstarter.java:136)
| At Freemind.main.FreeMindStarter.main (freemindstarter.java:56)
| panic! Error while loading default properties.
This is because the Java environment variable is not specified, locate the Java installation directory, and then enter it in the terminal (for OPENJDK6):
$ Export JAVA_HOME=/USR/LIB/JVM/JAVA-6-OPENJDK
You can also add directly to the system's environment variables, that is,/etc/profile the above row, and then restart the system later.
