Just did a clean install of LanCache Prefill on a new machine.
After the setup I ran:
su $USER
cd ${DATA_DIR}/(BattleNet|Epic|Steam)Prefill
which resulted in:
bash: syntax error near unexpected token `('
I then looked in the logfile where I noticed this:
---Version missmatch, installed v1.5.0, downloading and installing latest v1.6.1...---
---Something went wrong, can't download BattleNetPrefill v1.6.1, putting container in sleep mode---
