- Plesk Onyx for Linux
Debian/Ubuntu system update shows a warning:
CONFIG_TEXT: Fetched 17.5 kB in 2s (6082 B/s)
Reading package lists... Done
N: Ignoring file 'plesk.list.ai_back' in directory
'/etc/apt/sources.list.d/' as it has an invalid filename extension
W: Duplicate sources.list entry
W: You may want to run apt-get update to correct these problems
OR the following warning appears during microupdate installation or running apt-get update:
W: Target Packages (all/binary-amd64/Packages) is configured multiple times in /etc/apt/sources.list.d/50sw_autoinstaller.list:4 and /etc/apt/sources.list.d/plesk-migrator.list:1
This is a Plesk bug with ID PPPM-6049 that is planned to be fixed in future updates.
Until the issue is permanently fixed, the warning can be safely ignored.
As a workaround, connect to the server via SSH and comment out any repository line from
/etc/apt/sources.list* containing any of those words to avoid duplicates:
# grep -r "PMM_" /etc/apt/sources.list*
#deb [arch=amd64] http://autoinstall.plesk.com/debian/PMM_0.1.10 wheezy all
