Description Guillaume Pavese 2019-10-24 20:39:46 MDT

On Fedora 31 and preceding, I used to be able to call aliases defined in my .bashrc by using 'sudo -E'
Since update to sudo 1.8.28, 'sudo -E' seems to not preserve aliases from the calling user : "command not found"

Do you know what version of sudo you were running before?  I don't think that bash can preserve aliases between shells, though it can export functions into the environment so that sub-shells pick them up.

Comment 2 Guillaume Pavese 2019-10-25 03:29:42 MDT

I went from working sudo-1.8.27-3.fc31 to sudo-1.8.28-1.fc31

Comment 3 Todd C. Miller 2019-10-25 08:08:59 MDT

If you comment out the following line in sudoers sudo should behave the way you expect:

Defaults    always_set_home

In sudo 1.8.28 that setting will prevent HOME from being preserved which is why your .bashrc is not being read.

This is not due to any change in sudo itself, it is due to the addition of the always_set_home setting in the default sudoers file shipped by fedora.

I've attached a diff of the two sudoers files installed by fedora.  This is not the default sudoers that ships with sudo, it is a file maintained by the fedora project.

This is not due to a sudo bug, it is a change in fedora's sudoers configuration.

Thanks, I confirm that this was the problem
