Plesk for Linux kb: bug ext: migrator ABT: Group A

Applicable to:

  • Plesk for Linux

Symptoms

  • 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
    http://autoinstall.plesk.com/debian/PMM_0.1.10/jessie/all amd64
    Packages
    (/var/lib/apt/lists/autoinstall.plesk.com_debian_PMM%5f0.1.10_dists_jessie_all_binary-amd64_Packages)
    W: You may want to run apt-get update to correct these problems

  • The following warning appears during microupdate installation or running apt-get update:

    CONFIG_TEXT: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

Cause

This is a Plesk bug with ID PPPM-6049 that is planned to be fixed in future updates.

Resolution

Until the issue is permanently fixed, the warning can be safely ignored.

Nevertheless, the following workaround can be performed to get rid of the warning:

workaround

  1. Connect to the server via SSH;

  2. Edit file /etc/apt/sources.list*;

  3. Comment out any repository line from this file with a "#" character containing any of the following words:

    CONFIG_TEXT: PSA_
    PMM_
    SITEBUILDER_

    For example:

    # grep -r "PMM_" /etc/apt/sources.list*
    #deb [arch=amd64] http://autoinstall.plesk.com/debian/PMM_0.1.10 wheezy all

    Hi @Rob, it seems you have commented out all of them correctly. Could you run the update again and paste the error here and also file mentioned in the error, such as /etc/apt/sources.list.d/***** ?

    You can also ignore these errors which will be fixed in future updates.

    I included that at the beginning of the output I provided.  If you need something else, please let me know from which log you are looking for.
