It is not uncommon for some Linux distributions to have older versions of packages and repositories, including Deepin Linux. This is because Linux distributions, including Deepin, prioritize stability and security over having the latest versions of software. MyTHDHR Time Detail
However, it is possible to install newer versions of packages and repositories on Deepin Linux through various methods. One way is to add additional repositories to your package manager configuration. This can be done by adding a new repository file in the "/etc/apt/sources.list.d/" directory or by using a graphical package manager tool.
Another option is to download and install software directly from the developer's website or by using package managers like Snap, Flatpak or AppImage. These package formats provide a way to package and distribute software independently of the distribution's package manager, so you can have access to the latest versions of software.
Regarding the issues with Opera and other packages, it is possible that there are dependencies or compatibility issues with your system. You can try installing missing dependencies or updating your system to the latest version to see if it resolves the problem. Alternatively, you can seek help from the Deepin Linux community or from the support channels of the software you are trying to install.
