#3385 closed bug (Fixed)

TypeError: a bytes-like object is required, not 'str'

Python 3.7 libtorrent 1.2.5 boost 1.72 FreeBSD 11.3-RELEASE-p7 (FreeNAS.amd64)

    _file.write('%d\n' % os.getpid())
TypeError: a bytes-like object is required, not 'str'

changing the line to

_file.write(b'%d\n' % os.getpid())

allows it to get further, but then I get an OpenSSL error which I'll make another ticket for.

OS : Ubuntu 20.04.1 (xubuntu-desktop) PPA : "ppa:deluge-team/stable"

To start deluge as a daemon, I created a systemd service file "/etc/systemd/system/deluged.service" containing

ExecStart=/usr/bin/deluged --port=56789 --do-not-daemonize --pidfile=/tmp/

This gives the fatal failure "TypeError: a bytes-like object is required, not 'str'" on starting the service.


Remove the "--pidfile=/tmp/" from ExecStart.


The file "/usr/lib/python3/dist-packages/deluge/" contains

    326           # Write pid file before chuid
    327           if options.pidfile:
    328               with open(options.pidfile, 'wb') as _file:
    329                   _file.write('%d\n' % os.getpid())

Line 328 enforces BINARY WRITES to the PID-file. But a string will be written in line 329. This causes a write-error (and ultimately the fatal failure).


Change line 328 in

    328               with open(options.pidfile, 'w') as _file:

The 'wb' is changed in 'w'. :)
