I will try to use a symlink from libzip.so.4 to libzip.so.5 (but this is not a good solution for everyone)

With the symlink to libzip.so.5 the wrapper is working on my system, but still this is not a good solution
I have a running task and the additional files are downloaded from git, this did not work without libzip.so.4

edit:
with LODA v2510.16 x86_64-pc-linux-gnu this issue does not happen, so a local installed libzip was not neccesary

Looks like the next system with the same issue
Debian GNU/Linux 13 (trixie)
wrapper_26019_x86_64-pc-linux-gnu
libzip.so.4 => not found

installed is
/usr/lib/x86_64-linux-gnu/libzip.so.5
/usr/lib/x86_64-linux-gnu/libzip.so.5.5

edit:
Fedora Linux 42 (Workstation Edition)
same issue

installed is
/usr/lib64/libzip.so.5
/usr/lib64/libzip.so.5.5

edit2:
on my Kubuntu 25.04 I found an older app version
wrapper_26015_x86_64-pc-linux-gnu
here the wrapper has no shared libzip object (shared library) required

The wrapper app is provided by BOINC. You can open an issue at https://github.com/BOINC/boinc/issues

Still getting computation errors on all tasks (strangely on my better machines) - for example:

I have Git installed. This is a Ryzen 9 3900XT with the latest Windows 11.

Here to, all systems ~70% fails most after a few minutes but often also after 80%+ completion.
If this keeps on I'm switching projects..

Same on my side. Failed rate is much higher since yestraday and all ends with same error like this:

I deleted some corrupt data from the API server.

Hi

FYI I have a high rate of errors on my Intel iMac.

All my work errors out with

I have now installed the libzip package and it supplies libzip.so.5.5 with a symlink to libzip.so.5

I will have to make a symlink to libzip.so.4 to see if that gets it working

@Jerome: Did you install a new BOINC version? Try resetting the probject. Your error is:

2025-11-02 04:00:43|INFO |Checking environment

I had noticed some Loda tasks were working fine, and some others were failing after some time (but not immediate) like this one, then I reinstalled the *same* version of boinc 8.2.5 because after a reboot I had a file rights error while starting boinc (I don't remember if it was specifically mentioning loda or not, I'm used to such errors when I add some app_config files, but I don't have any for loda), now I just tried to reset the project on your advice, I can see it downloaded application files again

but I tried to get some tasks again and they all fail after a few second, like this one.

Same for me, all systems are generating mostly errors except one strangely enough (the one with the least cores/threads :?)
I'm switching projects for now but will be back when its stable again.

There were two general issues: corrupt data and an API server outage. Both are fixed now.

Tried the project again today.. still many errors. Sometimes after a few secs but often after several hours and seems for many jobs I'm not the only one wasting resources.
I will finish the running tasks and move over to another project.

I really tried, but since today again all tasks running into computation error. I wanted to end up in the top 5 users but this way it's undoable. I might try again in a few months from now but for now I'm quitting this project.
