It's a bit odd, because I can't reproduce the issue from my side. Could you please give me more details about your working environment, it will be helpful to track the root cause of this problem.
Otherwise, you'll find linked here the same issue with two proposed workarounds.
This may help you find a solution for your problem.
Did you try to do manually the unzip following these steps:
unzip the file stm32cube_fw_wb_v1101.zip
Rename the unzipped folder name to STM32Cube_FW_WB_V1.10.1
unzip the file stm32cube_fw_wb_v1100.zip
delete the zip-files in the Repository folder
Start the STM32CubeIDE software again.
Select Help -> Manage Embedded Software packages, select ‘Refresh’ in the Embedded Software Packages manager and check if the unzipped files are visible.
Thanks for the inputs you provided, I still can't reproduce the problem. It is strange that it is not working from your side, but let's see what can we do to resolve this misbehavior.
Let's first recapitulate the problem: so you're not able to generate because of the missing STM32Cube_FW_WB_V1.10.1 firmware in you repository and when trying to install this package, the download process is ending with the error "Target directory already exists" (same for STM32F4 firmware) . Please correct me if I misunderstood.
As indicated by the error message, a directory with the CubeFW name exists in the repository, please inspect the Repository folder, and delete the unexpected directory.
Backing to one of your screenshots:
I can see here that STM32Cube_FW_WB_V1.10.1 firmware is correctly installed. Thus, normally the misbehavior is corrected.
Otherwise, backing to the following screenshot:
Normally the framed folder will disappear automatically after the end of the download process. Does this happens in your case or do you always see this file in your repository folder?
PS: Trying to delete the "TMPUPD_.... " folder above during firmware install corrupt the unzip process and in this case the "Target directory already exists" error may occur. In addition, trying to modify the content of this folder fails the install process.
