Resolved Extension Manager Missing - Can't install Extensions after upgrade

[Bebber]

After successfully update from 17.5 to 17.8 I'm not able to install custom extension anymore
Actually, I can't find an extension manager menu too but if I manually choose path "modules/catalog/index.php/catalog/featured", choose an extension to install, and then try installing itself
I get a strange message:
Error: Task 'install' is not registered.
Extensions like Let's encrypt or Advisor (installed via Component) works well.
Does anyone have an idea on how to get Extension manager working again?
(did my search on kb but found a similar issue just for windows)
Thanks a lot

Maybe incomplete installation?

# plesk repair installation

Thank you s much for the reply!
I tried it, problem persists (it's strange cause if I manually upload an extension it works)
Looked at repair logs and found just this WARNING messages:

I really don't know if it's related,

I have the exact same issue with the disappearing extension manager on linux, though after the upgrade the extension manager was there and i looked it though a few minutes later it was gone.
I've tried "plesk repair installation" and a server reboot but no luck so far, also no errors in the repair logs.

Hello

i have the same problems as Mark@beeldr.

edit: maybe my problems is : Debian 8.1

 

[Bebber]

I don't think is anything related to OS, CentOS here.
BTW if you need to install an extension, as a temporary workaround, just go to:
https://YOURDOMAIN.EXT:8443/modules/catalog/index.php/installed > Upload extension
And then upload the specific extension previously downloaded from Plesk Extensions

 

[HenningM]

Same here, with CentOS 7.
Plesk 7.8 Update #5

Well this should be reported as bug Important - PLEASE FOLLOW THIS INSTRUCTION IF YOU BELIEVE THAT FOUND A BUG!
it seems to hit more and more Issue - Extension manager lost.

To help the developer it is always helpful to give as mutch information to them migrated from Version (Plesk & OS) -> Version (Plesk & OS)
@IgorG - will you guide them?

For my interests does the comand on CLI still works like

# plesk bin extension -l

If someone of you have this issue on a non productiv Server - non critical domains on it can try for example this - the path is from a Centos7 Server and might be different on you system:

# plesk bin extension -i /usr/local/psa/var/ext-catalog.zip

otherwise wait for Plesk guidance or better ideas

 

[HenningM]

I can confirm, that the CLI command works.
It wasn't an upgrade or migration on our side. It was a normal update from Plesk.

Kind regards
Henning

Tried this solution and my extension manager is working again:
Extensions menu is missing after the upgrade from Onyx 17.5 to Onyx 17.8 on Linux

We often have problems with Plesk transition updates.

i have the same problems as Mark@beeldr.

OS : Cent OS 6.8 (64 Bit)

80% of extensions do not work with update

example

(D)DOS Deflate Interface (Plesk)
Linux Malware Detect Manager (Plesk)

I also had troubles with LMD, but AFAIK they're actually working to make the extension compatible with 17.8

I love plesk panel I've been using it for 10 years. But the updates are really messy. it is very tiring to do a zero install on major updates and re-install 50 web sites. hope these problems will improve over time
