I can't upload sketches using the USB, but I can do it by using an FTDI programmer while using the USB the Arduino ide show error

error: Sketch uses 257672 bytes (24%) of program storage space. Maximum is 1044464 bytes. Global variables use 26572 bytes (32%) of dynamic memory, leaving 55348 bytes for local variables.

How can I overcome this issue?

the FTDI usb ttl interface is a bad one. We know this on tasmota (github) too. Use an usb ttl adapter based on CH340, the only one whoch work with all types of boards. Look at ali express and you will find the links for the drivers too. For linux you have to setup your interface correctly. Also ask google for it.
