Issue Plesk update problem / UI & command line / Loaded plugins

[Erwan]

Hi all,
I have a problem with a plesk update (Centos 7.9).

If i use the GUI (/admin/update/products/), the page turns continuously and never stops.
With command line :
#/usr/local/psa/admin/bin/autoinstaller
...
1. ( ) Install the latest available update
2. (*) Add/Remove components
====> F
...
...

gpg-pubkey-914bdf7e-55c05220 gpg(Plesk Team <[email protected]>)
gpg-pubkey-4520afa9-50ab914c gpg(Atomicorp (Atomicorp Official Signing Key) <[email protected]>)
Loaded plugins: fastestmirror

It stays on this line: Loaded plugins: fastestmirror
One hour for the last attempt before i kill.

Nothing else.

Does anyone have an idea?

Strange, I had encountered the same problem 4 years ago for another server.

Resolved - Plesk installer blocked on "Loaded plugins: fastestmirror"

Hello, When i made a plesk upgrade with: #plesk installer it's blocked on "Load plugins: fastestmirror": Select the products to install and their versions =============================================================================== The following product versions are available: 1. Plesk...

Do you see more information in /var/log/plesk/install/autoinstaller3.log?

 

[Erwan]

No only my kill

No idea?
We have in fact two servers with this problem at this moment.

No way to have more detailed logs?

 

[Monty]

• Do you see anything relevant in /var/log/messages?
• Any hints in /var/log/plesk/panel.log?
• What happens if you run yum update ?

 

[Erwan]

Nothing in /var/log/messages
Nothing in /var/log/plesk/panel.log

Yum update could not be executed because of a python update script still in progress.
I kill it.

Always the problem with /admin/update/products/.

I executed yum update.

After it, Pleks update works.
So resolved. Thank you.

 

[Monty]

Glad to hear.
Maybe you have the "yum-cron" package installed which might be running in the background, blocking the Plesk updater. If you don't need it you can disable it with:
# systemctl stop yum-cron
# systemctl disable yum-cron

 

[Erwan]

Ok.
Example:
/usr/bin/python /usr/bin/yum --enablerepo=tortix-common list updates aum ipset mod_security

 

[Erwan]

For the second server, the Yum update remained suspended:
...
Nettoyage : bind-license.noarch - 67/100
Nettoyage : python-firewall-0.6.3-12.el7.noarch - 68/100
Nettoyage : containerd.io.x86_64 - 69/100

The problem seems to come from a task is not responding (id=1938- Advanced monitoring that I wanted to install several weeks ago but without success).
I kill it.

An i stop the yum process... (i think I should not have..)

After that, when i connect to Pleks update UI, i have the message: Can't connect to backend: No such file or directory
I've solved it with: Unable to open Updates and Upgrades menu on Plesk for Linux server: Can't connect to backend: No such file or directory

After, i can access to the Plesk update UI. I've made a first update (18.0.34 updates).
All ok.

After, i want update version to 18.0.37.
And i have this message:

Plesk pre-upgrade check
ERROR: Your package system contains duplicated packages, which can lead to broken Plesk update:

...

I try to rollback with yum history but it doesn't work (errors).

How can i resolve this duplicated packages problem?

Thank you.

That looks bad, you have a mix of packages on your servers.
You can try to run yum-complete-transaction (if it's not available, install it with yum install yum-utils). And if that doesn't resolve the issue I suggest you contact Plesk support as this is not really easy to resolve and just trying something may break your server.

 

[Erwan]

Ok.
I should have done the yum-complete-transaction before updates.
I no longer had this order in mind.

Si, it detects duplicate packages and offers to delete them:

There are 2 outstanding transactions to complete. Finishing the most recent one
The remaining transaction had 31 elements left to run
..
Delete
bind-export-libs x86_64 32:9.11.4-26.P2.el7_9.3
bind-libs-lite x86_64 32:9.11.4-26.P2.el7_9.4
...

Total: 1.1G

Can I run the command securely?

 

[Monty]

You only need to run yum-complete-transaction if a previous yum transaction was aborted for some reason and that apparently was the case on your system.
I can't tell you if you should run it. It may break something and you may end up having an unusable system or missing packages/dependencies.

If you're feeling brave, take a snapshot of the VM, run the command and immediately check if everything is still working. Otherwise rollback the snapshot and let Plesk support or somebody else help you.
