upgrade from 6.4-4 to 7.3-3 according to wiki fails

[jppialasse]

following https://pmg.proxmox.com/wiki/index.php/Upgrade_from_6.x_to_7.0 to upgrade the process fails.

at the end of the upgrade process you get

dpkg: error processing package pmg-api (--configure): installed pmg-api package post-installation script subprocess returned error exit status 1 dpkg: dependency problems prevent configuration of proxmox-mailgateway: proxmox-mailgateway depends on pmg-api (>= 7.3~); however: Package pmg-api is not configured yet. dpkg: error processing package proxmox-mailgateway (--configure): dependency problems - leaving unconfigured Processing triggers for libc-bin (2.31-13+deb11u5) ...

Errors were encountered while processing: pmg-api proxmox-mailgateway E: Sub-process /usr/bin/dpkg returned an error code (1)

it happends that trying to then do apt install proxmox-mailgateway you get a more verbose message telling that pmg-api fails because of a masked service

workaround is

systemctl unmask  pmg-smtp-filter
apt install proxmox-mailgateway

ulitmately I feel like this is either a documentation bug either a bug in the post script that test for service not being masked...

could you please share the complete /var/log/apt/term.log (and /var/log/apt/history.log)?

do you have any modifications on the system - config wise?

thanks!

Ok - I think we found out what happend:
* with the changes between 7.2 and 7.3 we modified the postfix templates - this results in `pmgconfig sync -restart 1` (which is called by the postinst script of pmg-api) to try to reload postfix - which in turn fails due to the masking from the guide

There is a patch on the pmg-devel list which addresses the issue:
https://lists.proxmox.com/pipermail/pmg-devel/2023-March/002385.html

once it has been applied the issue should not occur anymore

Thanks for the report!

Hello,

Is this already fixed?
I need to do the upgrade this weekend

Br,

 

[Stoiko Ivanov]

seems it did not get applied until now - the workaround described above should still work though

Thanks for the reminder!

Can you please give a follow up when this is fixed so i can safely do the upgrade process?

Br,

pmg-api 7.3-4 contains the fix and is available on the pmgtest repository:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmg_package_repositories

I cannot tell you when exactly it will transition to pmg-no-subscription or pmg-enterprise.

I hope this helps!
