Solution

Extend zip-archive file size limit from 1MB to 2MB:

1. Become root:

   sudo su

2. Open the file for modification:  /opt/kaspersky/apt-request-utils/lib/request_utils/zip_checker.py

3. Find the line in the file:

   def verify_zip(file_to_check, files=(), max_size=(1024 * 1024))

4. Change the max_size value to (1024 * 2048)

   def verify_zip(file_to_check, files=(), max_size=(1024 * 2048))

5. Save the changes.

6. Restart uwsgi:

   systemctl restart uwsgi

7. Clear the browser cache, reload page and check if issue is now fixed.
