When I try to install Sublime Text 3 from a downloaded .deb file I get errors:
The installation or removal of a software package failed
Data files for some packages could not be downloaded
The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.
This is a permanent failure that leaves these packages unusable on your system. You may need to fix your Internet connection, then remove and reinstall the packages to fix this problem.
sudo apt-get install ttf-mscorefonts-installer (...) ttf-mscorefonts-installer is already the newest version.
Can I omit somehow this problematic Software Center?
[EDIT] It seems it is possible to omit Software Center:
sudo dpkg -i DEB_PACKAGE
