Hi,

perhaps this problem is described somewhere other in the community, but I can’t really find it ☹  
If I try to upgrade manually ( pakfire upgrade ) I get  
`DOWNLOAD ERROR: The downloaded file (pakfire2/2.25/paks/core-upgrade-2.25-157.ipfire) wasn't verified by IPFire.org. Sorry - Exiting...`

Trying to verify the download file results in

```auto
gpg --verify /opt/pakfire/tmp/core-upgrade-2.25-157.ipfire
gpg: Signature made Mon Jun 21 11:20:46 2021 CEST using RSA key ID D713594B
gpg: Good signature from "IPFire Pakfire Package Signing Key <pakfire@ipfire.org>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
Primary key fingerprint: 3ECA 8AA4 4782 08B9 24BB 9620 6FEF 7A8E D713 594B`

```

Looks like the signature are lost.  
Or is it a memory problem?

It was a memory problem.  
Time to change the system 😉
