Hi,

I am getting the below error message while trying to update plesk from 18.0.40 to 18.0.41.

Installation started in background
File "/usr/local/psa/bin/yum_install", line 33
print msg

SyntaxError: Missing parentheses in call to 'print'. Did you mean print(msg)?

Hi,

In my case there is no errors on mysql repo's in the system and we are not using Mariadb repo as well. It says error on below

File "/usr/local/psa/bin/yum_install", line 33
print msg
^

Plesk is designed to operate under Python 2.7, but looks like python 3+ is in use:

# python --version
Python 3.6.9

# ls -al /usr/bin/python
lrwxrwxrwx 1 root root 9 Sep 11 19:32 /usr/bin/python -> python3.6

Replace the Python symlink with 2.7 binary:

1. Run the following command:

# ln -snfT python2.7 /usr/bin/python

2. Confirm the change:

# python -V
Python 2.7.17
