It not a real bug… It is caused due to how Ubuntu threats the syslog user…
syslog is an “system” user with permissions set to nologin:
During boot Hestia runs a cronjob it initialise the sftp “filesystem”
It checks if a user has “ssh” access set to no login:
syslog:x:101:103::/home/syslog:/usr/sbin/nologin
2nd check:
If it has an user directory in /home/ folder
If those 2 things matches it call v-add-user-sftp-jail
There we have added 1 check if the user is “Hestia” user and this check fails and an “error” is created.
Even it works as intended…
