In this case, I demonstrate using the example of preview 5.11.2 but an absolutely similar error falls out on 5.11.1, before that it was 5.10.1. Everything was fine, I decided to upgrade, but as a result I was left without anything at all.
Error during the installation process (preview.qt.tools.qtcreator): Error retrieving from the installer: //preview.qt.tools.qtcreator/4.6.84-0-201807050557preview-qtcreator.7z archive: insufficient memory
Repeating does not help, when you skip, such errors continue to fall out. On the disk about 15 gigs is free, there is also enough opera. Ubuntu 04/18/1 x64 Thank you if anyone knows where the dog is buried
Next comes another
