I've just run into a scenario not listed above in which left me
without /usr/bin/ruby afterwards. This scenario is likely not
happening during an dist-upgrade from Wheezy to Jessie as it's planned
now, but may still hit other people who are running unstable.
After I've read this changelog entry, I installed glark (which is
currently ruby1.8 only) again to notice when there's an updated
version working with a newer release of Ruby.
Afterwards, how-can-i-help threw strange errors:
/usr/lib/ruby/vendor_ruby/debian.rb:24:in `require': no such file to load --
debian_version (LoadError)
from /usr/lib/ruby/vendor_ruby/debian.rb:24
from /usr/bin/how-can-i-help:20:in `require'
from /usr/bin/how-can-i-help:20
E: Problem executing scripts DPkg::Post-Invoke '[ ! -e /usr/bin/how-can-i-help
] || /usr/bin/how-can-i-help'
I noticed that /usr/bin/ruby points back to ruby1.8:
update-alternatives: using /usr/bin/ruby1.8 to provide /usr/bin/ruby (ruby) in
auto mode
I'm not sure if this is a bug in update-alternatives as it seems to
happily overwrite a file which was installed by a package -- I would
expect that it should prevent that.
At least I think, it's worthwile to consider Marga's idea of uploading
ruby1.8 once more to remove that call to update-alternatives to
prevent this kind of issue.
Another option I can imagine is to keep the update-alternatives
mechanism for one more release but with just one alternative.
... or make update-alternatives not to overwrite package-installed
files. That's dpkg-divert's job.
I'm neither sure where to actually file a bug report for that issue
nor which severity it should have (I can imagine everything, from
minor to grave -- as it deletes a file installed by another package).
Any advice or comment is appreciated.
Regards, Axel
