I have installed memcached and libmemcached-dev with the package manager from debian 10 and also pylibmc and django-pylibmc with pip3. But seahub does not work with memcache anymore, it gives UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe3 in position 1: ordinal not in range(128) in the log file.
I have to decomment it in conf/seahub_settings.py, then seahub works, but without memcache of course:
#CACHES = {
‘default’: {
‘BACKEND’: ‘django_pylibmc.memcached.PyLibMCCache’,
‘LOCATION’: ‘127.0.0.1:11211’,
}
#}
Memcache worked for years before upgrade. I started using it with seafile 4.x.
