<!-- Describe the issue -->

Issue

Bitcoin-qt will not launch, whether called from command line (bitcoin-qt) or via desktop launcher. The process does not terminate but hangs without clear error in CLI or journal logs.

<!--- What behavior did you expect? -->

Expected behavior

Bitcoin launching and displaying graphical interface (or failing with error messages/output).

<!--- What was the actual behavior (provide screenshots if the issue is GUI-related)? -->

<!--As above - bitcoin-qt hangs.-->

<!--- How reliably can you reproduce the issue, what are the steps to do so? -->

Reproducibility

Add bitcoin PPA then attempt to launch bitcoin as above.

<!-- What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? -->

Software Setup

• software version: 0.17.0 (cosmic2)
• installation method: via bitcoin PPA

<!-- What type of machine are you observing the error on (OS/CPU and disk type)? -->

Hardware Setup

• OS: Ubuntu 18.10 (new install)
• Hardware: Purism Librem15

<!-- Any extra information that might be useful in the debugging process. -->

Additional Information

No debug information to present.

Please advise if specific additional information would be of utility.

EDIT: for formatting

software version: 0.17.0 (cosmic2)

Since you build from source, you could try to build from 1e49fe450dbb0c258776526dba3ee583461d42ff, which is unfortunately not yet tagged in a release, but fixes the issue you describe here.

An alternative would be to compile the dependencies (including qt) from ./depends.

Could you please provide any additional information? I don't see how the two items in the changelog relate to this. Thanks for any clarification.

Sorry, I was linking to the HEAD of the 0.17 branch. You can see more commit here: https://github.com/bitcoin/bitcoin/commits/1e49fe450dbb0c258776526dba3ee583461d42ff

Thanks, I presume you're referring to this: https://github.com/bitcoin/bitcoin/commit/b0e88b89149f2aaf7c2eb23524655461214130ee

Unless I'm missing something seems like this breaks bitcoin core qt on most modern platforms. Thus hope this gets released/tagged soon. Thanks for the response and clarification.

this is pretty shocking: the official binary has been borked on many platforms - and badly, with zero indication of the nature of the problem. Why is this closed?! @MarcoFalke , do you know is there any ETA for a release?

Checkout v0.17.0.1 doesn't work too on Fedora 29.

This was fixed in v0.17.1
