apt upgrade - primary key - no binding signature

[tak21]

Dear all,

I am using SoftMaker NX with debian trixie and I have a warning every time I am updating my system:

Code: Select all

https://shop.softmaker.com/repo/apt stable InRelease
/usr/lib/python3/dist-packages/apt/cache.py:565: Warning: W:https://download.sublimetext.com/apt/stable/InRelease: Policy will 
reject signature within a year, see --audit for details, W:https://download.sublimetext.com/apt/stable/InRelease: Sub-process 
/usr/bin/sqv returned an error code (1), error message is:
Signing key on 1EDDE2CDFC025D17F6DA9EC0ADAE6AD28A8F901A is not bound:
           primary key
  because: No binding signature at time 2025-05-13T05:32:15Z
  because: Policy rejected non-revocation signature (PositiveCertification) requiring second pre-image resistance
  because: SHA1 is not considered secure since 2026-02-01T00:00:00Z, W:https://shop.softmaker.com/repo/apt/dists/stable/InRelease:

  res = self._cache.update(fetch_progress, slist, pulse_interval)

Can you please have a look and are there plans to upgrade the signing key?

Best, Thomas
