Install using tar archives
There is a separate tarball for ARM64 processors.
Unpack the pycharm-*.tar.gz file to a different folder, if your current Download folder doesn't support file execution:
tar xzf pycharm-*.tar.gz -C <new_archive_folder>
The recommended installation location according to the filesystem hierarchy standard (FHS) is /opt. To install PyCharm into this directory, enter the following command:
sudo tar xzf pycharm-*.tar.gz -C /opt/
To verify integrity of the downloaded archive, use the SHA checksum linked from the Download page.
Switch to the bin subdirectory:
cd <new archive folder>/pycharm-*/bin
Run pycharm.sh from the bin subdirectory.
