apt-get tries to downgrade pacakges on MD

[stallione]

not sure how to troubleshoot this issue but two of my MDs want to downgrade the installed packages every time I run apt-get upgrade

Any ideas? (The install went fine, I even rebuilt one of the MDs in question)

I see two possibilities:

1. Update your core and re-run /usr/pluto/bin/Diskless_CreateTBZ.sh then rebuild your MDs.

or

2. Remove the entry "deb file:/usr/pluto/deb-cache/ ./" from /etc/apt/sources.list on the affected MDs and then update/upgrade them.

I'm not sure why this is happening.

The second solution you offered worked. What does it do? Does it ignore the downloaded cache?

Thanks!

I believe the /usr/pluto/deb-cache is a repository of .debs, used to build the diskless images, at the time you ran /usr/pluto/bin/Diskless_CreateTBZ.sh on your core. 

What is puzzling me is why apt isn't using the newer .debs from the online repos.

aha! I see what's going on.. on my core, the /usr/pluto/deb-cache folder has corrupt files. for example look at the last file, it has a '%' instead of a '.' and there are lots of files like this..

Can I safely remove all the files from here? Will it download all new files when I rerun the /usr/pluto/bin/Diskless_CreateTBZ.sh ?

[phenigma]

The script /usr/pluto/Diskless...TBZ.sh will re-create the MD images completely from scratch, including the /usr/pluto/deb-cache folder.

With the 'deb...' line removed from /etc/apt/sources.list the MD will not try to use files from that directory, you can use and update your MD as if nothing was different.  Apt's cache of downloaded .debs is still active and not affected by this change.

What remains is to determine why/when/how the filenames are being corrupted and by what.
