Dear all, I am working on a Linux machine on which the IT team tried to install Firedrake, but got the following error: Traceback (most recent call last): File "firedrake-install", line 766, in <module> check_call(["apt-get", "--version"]) File "firedrake-install", line 205, in check_call subprocess.check_call(arguments, env=env) File "/usr/lib64/python2.7/subprocess.py", line 537, in check_call retcode = call(*popenargs, **kwargs) File "/usr/lib64/python2.7/subprocess.py", line 524, in call return Popen(*popenargs, **kwargs).wait() File "/usr/lib64/python2.7/subprocess.py", line 711, in __init__ errread, errwrite) File "/usr/lib64/python2.7/subprocess.py", line 1327, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory Do you know what the issue is?
