Hi, I moved icinga from centos to ubuntu and I have isssue with this plugin. Before migratuin plugin was working, but on ubuntu 22.04 not working.
I tried updated new version of plugins but I have still same issue.

r/usr/lib/nagios/plugins/check_synology_disks.py --host xxxx --seclevel 'authPriv' --user monitoring --authkey 'xxx' --privkey 'xxx'

Hi,

this is caused by a breaking change within the pyasn1-library (etingof/pysnmp#438).

As quick workaround you can downgrade pyasn1 to a 0.4.x release (pyasn1==0.4.8) or try to replace pysnmp with the fork pysnmp-lextudio==5.0.30

Unfortunately the original pysnmp module is currently not actively maintained but there is an effort to continue the project as a fork under its original namespace (etingof/pysnmp#429 / pypi/support#2420).

I'll see how that goes and change the requirements.txt accordingly...
