Resolved Could not install the Site Import extension

[JohnZ]

Tried to install the Site Import extension on Plesk Obsidian v18.0.29_build1800200825.21 os_Ubuntu 18.04
(also failed while on v18.0.28)

This is the error message, looks like it has something to do with dependencies:

Could not install the Site Import extension - Failed

• The execution of post-install.php has failed with the following message:

After this, the import options are available but an actual import (of email account) fails.

How can I find more info? Or do you know how to solve this?

The log files were not helpful, but the last line in the error was key to finding the solution:

stderr: ERROR:__main__:Command '['apt-get', '-qq', 'update', '--allow-releaseinfo-change']' returned non-zero exit status 100

I ran the same command in the terminal (reduced output at [.....]):

# apt-get update --allow-releaseinfo-change

E: The repository 'http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_18.04  InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

So it was a failed apt-get update which I solved by removing /etc/apt/sources.list.d/isv:ownCloud:desktop.list.
After this change, I removed the Site Import extension and installed it again, now without problems.
