Automatically remove Proxmox “No Valid Subscription” message on upgrades

The Proxmox “No Valid Subscription” message re-appears after each Proxmox software update, even if you initially patched the pve-manager file. Since Proxmox is free software under the GPL, I do not like the connotation of the message, which makes it sound like one is using unlicenced software. If you want to use the community repository for updates and do not need commercial support, it is completely legitimate to run Proxmox this way. If you want to use the 'enterprise repository', please look into the attractive subscription options.

Check your /etc/apt/sources.list and make sure, that you are actually getting updates from the free Proxmox repository:

echo "deb http://download.proxmox.com/debian/pve buster pve-no-subscription" >> /etc/apt/sources.list

proxmox_noreminder.sh: the script automatically removes the Proxmox 6 “No Valid Subscription” message on upgrades by watching the relevant directory with incron. Incron is watching the directory, as it seems to trigger more reliably than watching only the file. A few files in this directory are replaced during each upgrade, but only one needs to be patched in this edition of Proxmox. The script also patches the Proxmox Support Tab with a more friendly message.

Initially backup & patch the files manually and confirm with diff, that the changes are as expected:

cp /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js.bak
    sed -i "s/data.status !== 'Active'/false/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js
    systemctl restart pveproxy.service

    # log  the changes
    diff /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js.bak /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js

Install Incron and only allow the root user

apt-get install incron
echo "root" >> /etc/incron.allow

and copy the script:

cp proxmox_noreminder.sh /usr/local/bin/proxmox_noreminder.sh
chmod +x /usr/local/bin/proxmox_noreminder.sh

Add the following in incrontab

incrontab -e
...
/usr/share/javascript/proxmox-widget-toolkit/ IN_CREATE /usr/local/bin/proxmox_noreminder.sh $#

Test with (in another terminal):

tail -f /var/log/syslog | grep incrond

tail -n 30 -f /var/log/incron.log

Reinstalling pve-manager should trigger incron:

apt-get install --reinstall proxmox-widget-toolkit

The above scripts & patches may have unforeseen consequences and automatic patching could harm your system. Always backup your Proxmox system before applying such changes! Proxmox may change the code at any time, making the patches useless or even counterproductive. Please make sure you understand the code before applying it to your system. Also, IANAL, and in my opinion the above Proxmox patches are permitted under the GPL, but if want to make sure, please consult a copyright lawyer in your jurisdiction.
