i586-poky-linux-g++: no such file or directory

Trying to move from MacOS to Linux (Catalina issue) I get a few warnings and then an error when installing the board; "Intel i686 boards" (Edison).

`Warning: file ....

Warning: file /home/jac/.arduino15/packages/Intel/tools/core2-32-poky-linux/1.6.2+1.0/i686/sysroots/x86_64-pokysdk-linux/etc/ld.so.cache links to an absolute path /etc/ld.so.cache

Setting it up.../tmp/tmp.DW6rUNYKds/relocate_sdk.sh /home/jac/.arduino15/packages/Intel/tools/core2-32-poky-linux/1.6.2+1.0/i686/relocate_sdk.sh
SDK could not be set up. Relocate script failed. Abort!
find: invalid mode ‘+111’`

Using the "create.arduino.cc" Web interface. With the Edison board I get an error when compiling:

`Detecting libraries used...

Solution please?
