Upgraded to 1.8.15 Now getting error, cant find ibreadline.so.6

Development Tools IDE 1.x

Hi Everyone,

I just upgraded the Arduino IDE to version 1.8.15 from I'm pretty sure I was using 1.8.5 before. Well after I did and tried to load the bootloader on an ATtiny85 I received this error:

avrdude: error while loading shared libraries: libreadline.so.6: cannot open shared object file: No such file or directory

So I looked online and found some threads about this and they suggest creating a symbolic link to
libreadline.so.6 by:

** ln -s /snap/gnome-3-28-1804/161/lib/x86_64-linux-gnu/libreadline.so.6.0** but I also get an error saying:

**sudo ln: failed to create symbolic link './libreadline.so.6.0': Read-only file system **

I am using Ubuntu 20.04 OS. Surely someone else has ran in to this before and was successful with coming up with a workaround.

Thanks in advance,
Chris

Hi @cwojohoitz. From the fact that you updated to an obsolete version of the Arduino IDE and that you mention snap, I suspect that you may have installed the Arduino IDE from a package repository.

Try using the official Arduino IDE 1.8.19 downloaded from the arduino.cc "Software" page:

Thank you.. I will give it a shot. Hopefully this solves my issue. Very frustrating!!! I just manually cleaned ALL references of Arduino off my laptop. Total PIA. Hope I never have to do that again..
