This remains an issue and I am looking for ways to debug it. It wasn't
always this way so it's quite possible that I did something to cause thi
s.

This was a timing issue. Adding the -a parameter to qvm-run made it go a
way.

[qubes-users] cannot create /tmp/qrexec-rpc-stderr.957: Interrupted system call

2020-06-21 Thread Sven Semmler
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Since a few days I have an issue with launching torbrowser or updates
on my whonix qubes.

Attempting to start torbrowser on anon-dvm fails 1 out of 5-6 times
without any message and the disp vm instance keeps running until I
shut it down.

I also have a bash script in dom0 I run once a day. Essentially what
it does is:

qvm-run --pass-io qube "sudo apt update && sudo apt upgrade -y"

... for all my templates.

At about the same rate as the above mentioned issue with the
torbrowser and anon-dvm I see this:

/usr/lib/qubes/qubes-rpc-multiplexer: 15:
/usr/lib/qubes/qubes-rpc-multiplexer: cannot create
/tmp/qrexec-rpc-stderr.957: Interrupted system call

Searching the web hasn't got me anywhere. It's not a terribly big
issue but it's kind of annoying over time. What can I do to debug it?

/Sven

For the "hot" side of the wallet you probably want the most recent 
version. For the "cold" / offline side it should not matter.


Also does anyone know if it's possible to have a split wallet with a 
bitcoin-core own node instead of relying on electrum?


Yes, see the howto using `electrs` or Electrum Personal Server:
https://github.com/qubenix/qubes-whonix-bitcoin

Note that for real privacy you will need to use JoinMarket. I don't know 
if Qubenix takes donations but if so it's definitely worth supporting 
him for putting together such an epic HOWTO!


Another thing is that a lot of menu options in electrum lead to web 
addresses and these very frustratingly open in Firefox inside the 
electrum VM. Is there a way to force these links to open in a dispVM?


That should work the same as changing the default URL for any other 
application. I think that is already covered in the Qubes docs.

The only recent Security Bulletin is about the new Intel CPU
vulnerabilities, but that isn't in the stable updates repository yet, so
unless you updated dom0 with testing repository, all your recent updates
are not security updates.


Thanks! Yes, I haven't seen any announcements, so that's why I was 
wondering.

Sorry for the late response, It took forever for the iso to download. 
IT'S WORKING! There is just one last problem. I can't get wireless 
working. Any ideas?

[qubes-users] Some questions about Electrum split wallet

2020-06-21 Thread 'Totally Zoid' via qubes-users
Hello!

The instructions for using Electrum split wallet on the Qubes website recommend 
installing electrum with dnf. However this gives electrum 3.3.4, which is not 
the most recent version, that is 3.3.8, available from electrum's website. 
Would it be safer to install the most recent version from the website? Also 
does anyone know if it's possible to have a split wallet with a bitcoin-core 
own node instead of relying on electrum?

Another thing is that a lot of menu options in electrum lead to web addresses 
and these very frustratingly open in Firefox inside the electrum VM. Is there a 
way to force these links to open in a dispVM?
