Hi, Please execute the dpkg -S libdlmcontrolui.so command to find the package name of this file.
Maybe you can try reinstall the org.deepin.downloader package to fix the problem.

I can reproduce this issue under a deepin v20.6 installation that were upgraded from v20.4 and then v20.5, with:

$ LANG=C apt policy libdlmcontrolui
libdlmcontrolui:
  Installed: 5.3.69.1-1
  Candidate: 5.3.69.1-1
  Version table:
 *** 5.3.69.1-1 100
        100 /usr/lib/dpkg-db/status
     5.3.69-1 500
        500 https://community-packages.deepin.com/deepin apricot/main amd64 Packages
     5.3.69-1 500
        500 https://com-store-packages.uniontech.com/appstore deepin/appstore amd64 Packages
     5.3.32-1 500
        500 https://community-packages.deepin.com/deepin apricot/non-free amd64 Packages
     5.3.22-1 500
        500 https://community-packages.deepin.com/deepin apricot/non-free amd64 Packages

The 5.3.69.1-1 version of the package libdlmcontrolui seems like a wrongly published version and it no longer exists, downgrade to 5.3.69-1 should do the trick.

You can try:

$ sudo apt install --reinstall libdlmcontrolui=5.3.69-1

or simply remove it and then reinstall it manually if you like. After reinstall it, it will looks like:

$ LANG=C apt policy libdlmcontrolui
libdlmcontrolui:
  Installed: 5.3.69-1
  Candidate: 5.3.69-1
  Version table:
 *** 5.3.69-1 500
        500 https://community-packages.deepin.com/deepin apricot/main amd64 Packages
        100 /usr/lib/dpkg-db/status
     5.3.69-1 500
        500 https://com-store-packages.uniontech.com/appstore deepin/appstore amd64 Packages
     5.3.32-1 500
        500 https://community-packages.deepin.com/deepin apricot/non-free amd64 Packages
     5.3.22-1 500
        500 https://community-packages.deepin.com/deepin apricot/non-free amd64 Packages

Let me know if you need any additional help.
