Dyalog Forums

Dear all,


I tried to install Dyalog on the new version of Rasperry OS (BULLSEYE).

I followed the instructions given but fail at the installation of the packges:

sudo apt-get install dyalog-unicode
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package dyalog-unicode

However, the installation of the interpreter alone (dyalog-unicode-180) works.

I don't know why, but it seems there is an issue when using bullseye repository in the dyalog.list file.
Replacing it with buster it works and dyalog-unicode installs the interpreter and ride.

After installation, I cannot start Ride 4.3:

Any hints would be appreciated.

Can you try launching RIDE this way?

/opt/ride-4.3/launcher --no-sandbox

Does that work?
John

This should work too. Maybe less insecure?

/opt/ride-4.3/launcher --disable-features=VizDisplayCompositor

Hi meijerjo,

The first solution is working:

pi@raspberrypi:/opt/ride-4.3 $ ./launcher --no-sandbox <- This is OK.

The second shows errors but starts RIDE as well:

pi@raspberrypi:/opt/ride-4.3 $ /opt/ride-4.3/launcher --disable-features=VizDisplayCompositor

../../sandbox/linux/seccomp-bpf-helpers/sigsys_handlers.cc:**CRASHING**:seccomp-bpf failure in syscall 0403
../../sandbox/linux/seccomp-bpf-helpers/sigsys_handlers.cc:**CRASHING**:seccomp-bpf failure in syscall 0403
../../sandbox/linux/seccomp-bpf-helpers/sigsys_handlers.cc:**CRASHING**:seccomp-bpf failure in syscall 0403

Should I register a bug at Ride GIT?

Interesting I get no error with the second command, but I am running Ubuntu Server on my RPi4, not Raspbian so your error might be distro specific.

I'm no expert but I think the no-sandbox command might be less secure, so I'd use the latter if it works apart from the warnings.
John

I think that this error is distribution specific.
Further I checked now in the RIDE Git.
The problem is already known (https://github.com/Dyalog/ride/issues/796)

There the workaround is: ride --disable-seccomp-filter-sandbox

Florian

Thanks for that information.
That flag works for me too, with no errors/warnings, under Ubuntu.

I think the original problem was of my making .. I added bullseye to the list of supported Raspberry Pi codenames when I uploaded the most recent set of 18.0 images for the Pi - and completely forgot about both RIDE and the dyalog-unicode images.

I have (I believe) added bullseye to the list of supported codenames for both these packages, and at the same time I've added a signature to all three images.

Please let me know how you get on with these !

I did remove interpreter and ride. Then I changed the dyalog.list file frombuster to bullseye.

Installation of dyalog-unicode works now correctly.

Thanks Andy.

However the start of ride still fails due to the problem I mentioned earlier in my previous post.

BR Florian

It looks like RIDE 4.3 will not run on bullseye.

We have therefore added the most recent pre-release of RIDE 4.4 to the Pi repos for bullseye, and we've updated the dyalog-unicode package to point to this.

So on buster and earlier you'll get 18.0 and RIDE 4.3, and on bullseye and later you'll get 18.0 and RIDE 4.4.

Jumping the gun slightly with RIDE 4.4, but it's due for release in the next few weeks, and is stable.
