I just noticed that 3.2.2-1 is on testing already, this is the first
package version to contain the fix, please update your system and
check if the issue persists.

Bug#964819: rsyncd fails to access some directories

2020-07-11 Thread Samuel Henrique 
Hello Winfried,

Thank you for reporting this issue,

Could you please check if the same issue happens with rsync 3.2.2-2 ?
This package is currently in unstable and it will reach testing in
about 24 hours.

Alternatively, you can do the following to test:
comment out (or remove) the following line from
/lib/systemd/system/rsync.service:
"ProtectHome=on"

Then restart the service and see if the issue persists.

This is upstream's changelog entry for 3.2.2:
"The default systemd config was changed to remove the ProtectHome=on
setting since rsync is often used to serve files in /home and /root
and this seemed a bit too strict. Feel free to use systemctl edit
rsync to add that restriction (or maybe ProtectHome=read-only), if you
like. See the 3.2.0 NEWS for the other restrictions that were added
compared to 3.1.3."

Regards,

Bug#964819: rsyncd fails to access some directories

2020-07-10 Thread Winfried Boxleitner 
Package: rsync
Version: 3.2.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

after upgrade of rsync from 3.1.3-6 to 3.2.1-1 backuppc stopped working:
error message:
>> 2020-07-05 07:38:32 Got fatal error during xfer (unexpected response: '')
>> 2020-07-05 07:38:37 Backup aborted (unexpected response: '')

to track down the problem, I issued rsync on the commandline as user "backuppc"

symptom:

1) mounted filesystem /usr/local/ NOT accessible;
  timestamp shows date of first mounting this filesystem
  sideeffect: the exclude file located under this mounpoint
  was not accessible to rsync.

  backuppc@host:~$ rsync  user@host::home_at_host
  d- 40 2020/07/07 11:33:27 .

2) home of root NOT accessible, although on same filesystem

  backuppc@host:~$ rsync -v user@host::root_at_host
