This has to be an issue on Jolla’s side there is no other explanation:
- Ubuntu 20.04 LTS
- Latest SDK (offline or online doesn’t matter)
- Latest virtualbox
Run the SDK, select 188.8.131.52 armv7hl as one of the architectures (for me it was the only one). You will get repeated “Hash error this is temporary please try again later” after the tool is installed, at around 17% completion.
I have been trying for about a week now.
For funzies I tried 184.108.40.206 with zero issues.
