Unsolved Online installer interrupts
The online installer downloads the packets in junks of ~45 MB and interrupts the download for 20-30 second just a few bytes before it reaches the target size. Downloading Qt takes ages and eventually fails with an error. I can't remember exactly what error (something with timeout).
How can I change the repository source? Are there any others mirrors?
Hm that's unusual.
Yes there are other mirrors, check out the offline installers.
Based on my own experience, you might as well use the offline installer.
You still have to download.
