NodeJS and Python selector page for end users is stuck on loading

• When accessing the NodeJS or Python selector apps from the end user’s cPanel, the page is stuck on loading:
• The following error is present in the logs or in the browser’s console:var pluginVersion = ‘cat: /usr/share/l.v.e-manager/version: No such file or directory

Environment

• cPanel.
• CloudLinux 8
• NodeJS 
• Python
• lvemanager between v. 7.11.8-1 and v.7.11.10-1

Solution

The fix has been released to rollout slot 3 – the command to update is:

yum update lvemanager --enablerepo=cloudlinux-rollout-3-bypass

Previous workaround:

create the /usr/share/l.v.e-manager/version file and put the version of lvemanager package there, for example:

# rpm -q lvemanager 
lvemanager-7.11.8-2.el8.cloudlinux.noarch 

# echo "7.11.8-2" > /usr/share/l.v.e-manager/version

If it did not help, reinstall alt-python27-cllib:

# yum reinstall alt-python27-cllib -y
