I have the same issue. Tried to upgrade from 2.4.2 to 2.4.4, now I have error 500 when trying to domain.com:8090. Websites working fine

It took me almost the whole evening to figure this out. In the end, this command finally worked:

bash <(curl -fsSL https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh)

Tip for others:

Run as root (sudo su - if needed)
Make sure curl or wget is installed
Use bash, not sh

It’s a pity there is so little clear support/documentation for this, as many users get stuck on simple issues like this. Please make it more visible in the official docs – it would save a lot of time and frustration for the community.

Thanks.

sh or bash it’s the same.
but anyway, after this, still getting this error:

Seems something wrong with upgrade, please check...
