I am creating a virtual environment using mkvirtualenv, and I get this error, where have I gone wrong?

$ mkvirtualenv data
New python executable in /home/usman/.virtualenvs/data/bin/python
Installing setuptools, pip, wheel...
  Complete output from command /home/usman/.virtualenvs/data/bin/python - setuptools pip wheel:

  • Thanks. This error arose for me after some updates and/or reinstalling citrix (icaclient). Any idea what specifically might have caused this (reset permissions of this file) ? – jessexknight May 03 '23 at 21:52

    @jessexknight Copying/installing file(s) with wrong permissions and/or wrong `umask`. – phd May 03 '23 at 22:13

This is probably because your file "mime.types" has not the sufficient permission status. Use the chmod command as mentioned earlier.
