As @paul-praet commented, the following seems to work:

  1. close IDE and terminate all java/gradle processes
  2. delete or move the jbr sub-directory from the idea-IU-*** directory
  3. start the IDE
  4. perform the update using "Check for Updates" menu entry

I fought with this for a while. There's a long thread here that suggested several things, none of which worked for me. In summary:

  • launching IDEA from a symlinked directory caused this for some people
  • some people were able to close all existing projects and apply the update from the welcome screen (it's available from a Configure | Check for Updates menu item on the bottom of the welcome screen).

None of that worked for me, so I eventually just downloaded a fresh full install instead of the patch :|

I did this before updating and it worked perfectly:

$ chmod 777 jbr/bin/java

Had the same issue when updating to 2021.2 For me none of the answers worked. The only thing that worked for me was to download Intellij from Jetbrains website and install it over the old one (replace)
