Welcome to the forum

As your topic does not relate directly to the installation or operation of the IDE it has been moved to the Programming Questions category of the forum

Error compiling for board Arduino Uno.

Your two topics on the same or similar subject have been merged.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Please create one topic only for your question and choose the forum category carefully. If you have multiple questions about the same project then please ask your questions in the one topic as the answers to one question provide useful context for the others, and also you won’t have to keep explaining your project repeatedly.

Repeated duplicate posting could result in a temporary or permanent ban from the forum.

Could you take a few moments to Learn How To Use The Forum. It will help you get the best out of the forum in the future.

Thank you.

Sounds like a corrupt board package. Use the board manager in the IDE to downgrade the AVR board package to version 1.8.3 and test. If that works, upgrade again to 1.8.6.
