Library installation hangs when multiple libraries are installed simultaneously

[DannyV1]

Describe the problem

Arduino IDE periodically checks if newer versions of any of the installed libraries are available via Library Manager. If so, it displays an "Updates are available for some of your libraries" notification.

If the user clicks the "UPDATE ALL" button, all updatable libraries are updated.

🐛 The multiple libraries update sometimes hangs forever without completing.

To reproduce

1. Use Library Manager to install outdated versions of multiple libraries.
2. Press the Ctrl+Shift+P keyboard shortcut (Command+Shift+P for macOS users) to open the "Command Palette".
   A menu will appear on the editor toolbar:
   
3. Select the "Arduino: Check for Arduino Updates" command from the menu.
   The "Updates are available for some of your libraries" notification will appear.
4. Click the "UPDATE ALL" button in the notification.
   Arduino IDE will now start to install updates of each of the outdated libraries, as indicated by a notification and messages in the "Output" view, e.g.,:

   Downloading Adafruit NeoPixel@1.15.1
   Adafruit NeoPixel@1.15.1
   Installing Adafruit NeoPixel@1.15.1
   Replacing Adafruit NeoPixel@1.12.4 with Adafruit NeoPixel@1.15.1
   Installed Adafruit NeoPixel@1.15.1
   Downloading Adafruit PN532@1.3.4
   Adafruit PN532@1.3.4
   Installing Adafruit PN532@1.3.4
   Replacing Adafruit PN532@1.3.3 with Adafruit PN532@1.3.4
   Installed Adafruit PN532@1.3.4
   Downloading Adafruit SPIFlash@5.1.1
   Adafruit SPIFlash@5.1.1
   Installing Adafruit SPIFlash@5.1.1
   Replacing Adafruit SPIFlash@5.0.1 with Adafruit SPIFlash@5.1.1
   Installed Adafruit SPIFlash@5.1.1
   Downloading Adafruit SSD1306@2.5.15
   Adafruit SSD1306@2.5.15
   Installing Adafruit SSD1306@2.5.15
   Replacing Adafruit SSD1306@2.5.13 with Adafruit SSD1306@2.5.15
   Installed Adafruit SSD1306@2.5.15
   

🐛 The update progress notification may stop showing any progress at some point, remaining forever in the state where it indicates updates are still in progress.

Workaround

Update each library individually, in sequence:

1. When you see the "Updates are available for some of your libraries" notification, click the "INSTALL MANUALLY" button instead of the "UPDATE ALL" button.
   Library Manager will open, with a list of the updatable libraries.
2. Click the "UPDATE" button on the first of the entries in Library Manager for a library you wish to update.
3. Wait for the update to finish, as indicated by the appearance of a "Successfully installed library ..." notification.
4. Repeat steps (2)-(3) until you have updated all the libraries you wish to update.

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

I Think the libraries that it hung up on were the ones that had the subscript _library on them (not sure about the case of the 'L' ), as when I checked that dir, the libs that it hung up on still had that subscript on it, waiting for me to remove it.
I can't be sure it was 100% the case though.

Had similar recently. Was endlessly waiting for a library that had already finished installing, but I'd started installing a second one without waiting for first (or it's dependencies, cant remember) to finish.
Couldn't ever get it to stop waiting, until eventually tried removing (because it succeeded installing) and then reinstalling the stalled library causing the successful install terminal message to be tracked and the libraries installing dialog to finally accept the library installed and close itself.
