    That does not look like error in ISPConfig. The updated files have syntax errors. Unless the files had broken download the system maybe is missing some interpreter? What show commands
    Code:
    apt policy mailman
    lsb_release -a
    apt update

    Sounds like your python environment is messed up. That class is provided by:
    Code:
    # dpkg -S /usr/lib/python2.7/ConfigParser.py
    libpython2.7-minimal:amd64: /usr/lib/python2.7/ConfigParser.py
    You might check what version(s) of python you have installed, and maybe force reinstall the libpython2.7-minimal package (if the package tools are working enough to do so).

    Hello @Jesse Norell , thank you very much for your response.
    Output

    Code:
    :~# dpkg -S /usr/lib/python2.7/ConfigParser.py
    libpython2.7-minimal:amd64: /usr/lib/python2.7/ConfigParser.py
    
    
    The "problem" is that install operations on apt are blocked for mailman error. Then, i can't do apt-get install --reinstall libpython2.7-minimal.
    Thanks

    I agree with @Jesse Norell , python probably is somehow broken.
    Have you changed python version? Has some python package been removed?
    What shows
    Code:
    apt policy libpython2.7-minimal
    dpkg --print-architecture
    
    You can put mailman in hold, so it is not updated, or remove the mailman package. Removing without purge does not remove the configuration files so it is easy to install it back when errors are sorted out. Read how hold is done and undone in chapter 4.2.3.

    Thank you @Taleman .

    Code:
    :~# apt policy libpython2.7-minimal
    libpython2.7-minimal:
      Installed: 2.7.13-2+deb9u5
      Candidate: 2.7.13-2+deb9u5
      Version table:
     *** 2.7.13-2+deb9u5 500
            500 http://security.debian.org stretch/updates/main amd64 Packages

         2.7.13-2+deb9u3 500
            500 http://httpredir.debian.org/debian stretch/main amd64 Packages
    
    :~# dpkg --print-architecture
    amd64
    
    
    I will test with remove and install mailman. Thank you very much.

    Depending on how important mailman is and the time you can have it down to fix things, you may want to make a backup before removing it.

    I found out that in the past, admins compiled by hand python 3.8
    then
    Code:
    :/etc/alternatives# ls -lah python
    lrwxrwxrwx 1 root root 24 Feb 22  2021 python -> /usr/local/bin/python3.8
    
    I solved with
    Code:
    update-alternatives --config python
    
    I choosed 2.7

    Thank you @Jesse Norell and @Taleman
