The auto-update from 2.3.2 to 2.3.3 seemed to go smoothly, however, library and board updates stalled. I tried restarting the IDE and doing the updates manually with no effect. After downloading and installing the Win 64-bit .exe all is good.
My Linux Mint 21.3 , 64 bit, with Arduino IDE 2.3.3 also had a stall while installing a new (small) library (Adafruit HX711). A restart of the IDE with a shortcut crashed... because I did not update my shortcut to the new appimage name. I corrected my shortcut and no stalling on library installations.
New name: arduino-ide_2.3.3_Linux_64bit.AppImage
I am also having libraries/board manager stalling after updating to IDE 2.3.3. I use Debian 12.6 (Bookworm with kernel 6.1.25). I do not use the root account. I use the AppImage version of the IDE. Version 2.3.2 worked fine but not 2.3.3. I have compiled and uploaded code to an Arduino nano esp32s3 with 2.3.3 but only after closing the app and later re-opening. It seems that library/board updates get stuck after the load process. In this condition, it is not possible to compile/load sources. I note that updates have been placed in the '/home/redacted-user/.cache/arduino-ide-updater/pending/' folder whilst downloading/make executable places the app in the '/home/redacted-user/Downloads folder - I have 2.3.3. in both now! Perhaps I should place the app in the /usr/bin folder? The file 'update-info.json' in the above mentioned pending folder has nothing but the 2.3.3 appimage name, the sha checksum and user rights token so I do not think that is a problem.
Same here! Linux Mint 21.3 Cinamon 64 bit. With IDE 2.3.3 I had every time a stall while installing a new board or libary. For install this, I downgrade to 2.3.2 (both versions on my Linux) and restart the IDE 2.3.3 without any problems.
Further to my message above, I have found a quirk that might (or might not) be a reason for the oddity.
I had three ESP32-S3 boards attached to /dev/ttyACM0, /dev/ttyACM1, /dev/ttyACM2. My Arduino Nano ESP32S3 was connected to /dev/ttyACM0 and selected - the other USB connected devices were powered on but not selected. Powering off /dev/ttyACM1 and /dev/ttyACM2 and selecting /dev/ttyACM0 seems to allow IDE 2.3.3 to start normally. I also note that a 'dfu ports' with 1-2.1.1 code followed by the Arduino nano ESP32 device name appears which I don't think was in IDE 2.3.2 - though perhaps I'm mistaken as I don't have that release any more..
Not sure if that is a clue or if that affects other users.
