Public bug reported:
When installing a new cloudserver (on Amazon EC2, if it makes a
difference), UFW completely hangs on any command, for example ufw
status. Interrupting it with Ctrl+C yields this backtrace:
Traceback (most recent call last):
File "/usr/sbin/ufw", line 130, in <module>
lock = create_lock(lockfile=lockfile, dryrun=pr.dryrun)
File "/usr/lib/python3/dist-packages/ufw/util.py", line 1112, in create_lock
fcntl.lockf(lock, fcntl.LOCK_EX)
KeyboardInterrupt
The line numbers are always the same.
The platform is Ubuntu Server 20.04 (Ubuntu 20.04.2 LTS), from the
Amazon image. I have not seen this bug on other servers. UFW is version
0.36.
