Salt-minion not upgrading

Question

I've a salt-minion who refuses to upgrade. When I try to update it, apt-get says that it is already the newest version. Others minions are updating without problems.

I've already tried to uninstall it and reinstall it.

Any hints?

Here follows salt-minion version, apt-get result and os version. Thank you.

Short answer: salt-call command is not a part of the salt-minion package. It is a part of the salt-common package. You probably have to upgrade this package to fix the problem.

Some background: to find out which command is actually being executed when you run salt-call you can use command which:

$ which salt-call
/usr/bin/salt-call

Now we can find out which package is the one installing /usr/bin/salt-call by running:

$ dpkg -S /usr/bin/salt-call 
salt-common: /usr/bin/salt-call

Hope this helps!
