Keys on reference message during update

[terroreek]

Hi All,

Heads up it seems with the recent perl update when you do an apt-get update you will get this error at the end of the output.

keys on reference is experimental at /usr/bin/apt-show-versions line 264.
keys on reference is experimental at /usr/bin/apt-show-versions line 359.


The relevant bug report
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=758287

its save to ignore, but apparently it may cause aptitude to appear to be be hung.

I just du which included new libperl5.20 with no such error. I du with apt-get, the bug report only mentions the problem is specifically with aptitude.

I do get this message with apt-show-versions

I only use apt-get and have just got the error

Apologies, I du last night and didn't notice the error and upgrade completed successfully. I just ran apt-get update and do have that message.

You could patch apt-show-versions with this diff, then the message is gone.

For a "noobie" like me a tutorial on applying patches from diff. If there's some guide easier than this, I'll really appreciate!

Save the patch from the post into a text file in your home directory and name it apt-show-patch

# cd /usr/bin

The updated apt-show-versions was pushed out last week.  You shouldn't have to patch it.
