@Schorsch: I think they fixed a few things in their packaging pipeline which made the postinst stuff obsolete.

I updated the PKGBUILD so it should build again. Not sure if there might be any functionality missing that was previously in the postinst script, but they seemed to either have removed or moved it somewhere I can't find it :)

@masterX244, Yea I noticed that too and I've started to troubleshoot it, however they either changed more things or something is simply wrong with the Picotech packages. I'll have to do some testing to see if everything still works if I just ignore all that stuff...

there are some breaking changes inside the package, the .deb changed a few things around. Build fails. (the stuff from line 38 to 45 of the pkgbuild is not working anymore)

@Schorsch I'm not on a fresh picoscope install so maybe that is the issue? I've installed it about 5 or 6 months ago.

@SadiQ Maybe I missed something, but this should already be done by the install script on the library package. I may have to double check...

Ok. Based on the picoscope7 thread it seems that someone smarter used the following which works for me:

cd /opt/picoscope/lib
for f in *.so*; do sudo patchelf --clear-execstack "$f" ; done

Now picoscope starts for me.

It seems that after some updates picoscope won't start for me: [sadiq@arch ~]$ /opt/picoscope/lib/PicoScope.GTK

I do see those links in the lib directory:

I saw an error when running a script:

[sadiq@arch scripts]$ ./picoscope7beta_postinst
[sudo] password for sadiq:
ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied

I did run all the scripts in /opt/picoscope/scripts/ with sudo and I didn't see any error from them after that. I also added +x on the .so.1.0.* files and that still didn't work. Any tips on what I missed?

Regarding the "File was saved on a PS3406B device" error and Send Report dialog on close, this can be fixed simply by saving a new "User Default PS Settings" file (Save button on the toolbar). I also had that damn bug for a long time, trying to find WHERE that file-saved-on-a-PS3406B-device could be... seems like it refers to the default config.

I don't get an entry for a Pico Bootloader...

When I first connect the scope I get

And then when starting the application:

No idea why it says "PicoScope 4000". I have a 3203D and only have the 3000a driver installed.
