Resolved Apt/PUM update on Ubuntu 16.04 failing with missing PHP 7.3 Release file

[steve_gh]

Hi all.

When trying to run apt update on our Ubuntu 16.04 Plesk servers in the last few days (since at least 6 May), the update fails with the following (end of output):

Hit:15 http://autoinstall.plesk.com/pool/PHP_7.1.33_96 xenial InRelease
Hit:16 http://autoinstall.plesk.com/pool/PHP_7.2.34_150 xenial InRelease
Ign:17 http://autoinstall.plesk.com/PHP73_17 xenial InRelease
Err:18 http://autoinstall.plesk.com/PHP73_17 xenial Release

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.

A warning email from Plesk Package Update Manager was also issued:

All affected servers are on Plesk Onyx Version 17.8.11 Update #95 on Ubuntu 16.04.7 LTS‬.

I looked at the details on the repository page at Index of /PHP73_17 and there doesn't seem to be anything to support Ubuntu 16.04 there (see Index of /PHP72_17 for comparison). Is that on purpose?

Our Plesk sources list is as follows:

# cat /etc/apt/sources.list.d/plesk.list
## Persistent repositories for Plesk Products.
deb http://autoinstall.plesk.com/ubuntu/PSA_17.8.11 xenial extras
deb http://autoinstall.plesk.com/ubuntu/PHP56_17 xenial all
deb http://autoinstall.plesk.com/ubuntu/PHP70_17 xenial all
deb http://autoinstall.plesk.com/pool/PHP_7.1.33_96 xenial all
deb http://autoinstall.plesk.com/pool/PHP_7.2.34_150 xenial all
deb http://autoinstall.plesk.com/PHP73_17/  xenial all

Could support for PHP 7.3 please be re-added? Or is there an alternate package source URL to use in the future?

Thanks!

Please remove all PHP records from your /etc/apt/sources.list.d/plesk.list and run

# plesk installer update

It should help.

Thank you!

Please note that Ubuntu 16.04 is EOLed already, and it would be better to consider an upgrade to the latest versions of Ubuntu and Plesk.

@IgorG Hi, I'm having the same issue as this user, I'm relatively new to ubuntu and its commands. how exactly do I remove the php records from /etc/apt/sources.list.d/plesk.list?

thank in advance and appreciate your help

 

[IgorG]

how exactly do I remove the php records from /etc/apt/sources.list.d/plesk.list?

Just use the text editor in command-line interface.
nano or vim, for example.

I have the same problem. In my source.list I had:

deb Index of /pool/PSA_18.0.34_5691 xenial extras

deb Index of /ubuntu/PHP56_17 xenial all

deb Index of /ubuntu/PHP70_17 xenial all

deb Index of /pool/PHP_7.1.33_96 xenial all

deb Index of /PHP73_17 xenial all

so I removed all except the 1st line.

When I run "plesk installer update" after the download, the script stops with the message:

“Retrieving information about the installed license key ... The latest version of the product (s) and all selected components have already been installed. The installation will not continue.”

what am I doing wrong? Thanks in advance for your help

You are on Obsidian, not Onyx.
Obsidian doesn't support 16.04 anymore.
