ReadyNAS 104 [6.10.8] - Python 2.7 has disappeared
Hi all,
I have a ReadyNAS 104. Last night I checked the dashboard and saw that firmware 6.10.8 was available to install, so I installed it. One of my apps stopped working, and some command-line investigation tells me that the relevant .py file that launches the service uses /usr/bin/python . That is a symlink to python2.7, which doesn't exist. python2.6 does exist.
It looks like Python 2.6 was installed in 2013, and the symlink to 2.7 was installed in 2015. My guess is that the firmware update removed Python 2.7 but didn't update the symlink to point back to 2.6, thereby breaking anything that used just 'python'. I can update the symlinks if necessary, although I don't know if the app will run correctly (I can look into that on the app's site) -- but my question is: what happened to 2.7? I know it's out of support, but why would a firmware update remove it but leave the older 2.6?
I did try installing 2.7 with 'apt-get install python2.7' (as root) and got this output:
Reading package lists... Done

Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
cups : Depends: libcups2 (= 1.7.5-11+deb8u8) but 1.7.5-11+deb8u6 is to be installed
cups-client : Depends: libcups2 (= 1.7.5-11+deb8u8) but 1.7.5-11+deb8u6 is to be installed

libpython2.7-stdlib : Depends: libpython2.7-minimal (= 2.7.9-2+deb8u5) but it is not going to be installed
python-minimal : Depends: python2.7-minimal (>= 2.7.9-1~) but it is not going to be installed
python2.7 : Depends: python2.7-minimal (= 2.7.9-2+deb8u5) but it is not going to be installed
systemd-cron : Conflicts: cron-daemon
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I'm wary of following the advice there because it looks like it wants to downgrade some things. However those things are mostly cups, which I may have installed myself (a few years ago I was experimenting with using the 104 as a print server after Canon stopped supporting Google Cloud Print).
So a follow-up: is cups installed as part of the usual firmware? If not, I could just remove it and be more likely to be able to install Python 2.7.
Thanks,
Steve

Update on the app: I've found that for the version I have, it requires Python 2.7 and above. So I can't just switch to running under 2.6.
PS I tried adding the 104 to this post with the "Associated Products" field, but I can't seem to make it show me any NAS products at all.

This is what I see when I look in my own OS partition:
find . *cups* | grep -i cups ./usr/lib/x86_64-linux-gnu/libcups.so.2 ./usr/lib/cups ./usr/lib/cups/backend ./usr/lib/cups/backend/smb ./var/lib/dpkg/info/libcups2:amd64.list ./var/lib/dpkg/info/libcups2:amd64.symbols ./var/lib/dpkg/info/libcups2:amd64.shlibs ./var/lib/dpkg/info/libcups2:amd64.postrmI have a lot more than that, even in /usr/lib, which makes me think I have in fact installed some extras at some point. Since I'm not using the NAS as a print server anyway, I wonder if I should just force the apt-get to update everything then -- it doesn't matter to me if cups breaks, as long as it isn't going to matter to some app that thinks it needs cups to work.
Thanks for the reply -- would you be able to check what you have in terms of /usr/bin/python* please?
