Title:
rsync 3.1.2-2.1ubuntu1.6 breaks compatibility with unison
2.48.4-1ubuntu1 on Bionic
Status in rsync package in Ubuntu:
New
Status in unison package in Ubuntu:
New
Bug description:
Rsync 3.1.2-2.1ubuntu1.6, when used by Unison using the copyprog
option in Unison, produces an error message and fails to sync files.
Rsync 3.1.2-2.1ubuntu1 succeeds in syncing files. I believe Rsync
3.1.2-2.1ubuntu1.5 succeeded but I no longer have the .deb file to
test with.
Steps to reproduce:
Create a unison profile similar to the one given below, to sync a
folder between a local machine and a remote ssh server. Both client
and server need the same Ubuntu and Unison versions, and I used
unpassphrased SSH keys for authentication. Place a test file in the
folder to be synced, then run 'unison profilename'.
Note that I have redacted domains in the below.
Unison profile:
label = Test Profile
root = /root/unison-test
root = ssh://fs2b.our.domain.org.uk//root/unison-test
# run repeatedly and fully automatically
auto = true
batch = true
copyonconflict = true
#repeat = 60
# the copy program must be manually specified in order to sync ACLs
copythreshold=0
copyprog = rsync -a -A -X --rsh=ssh --inplace --compress
copyprogrest = rsync -a -A -X --rsh=ssh --partial --inplace --compress
