       Status: New => In Progress

** Summary changed:

+ 
+ [ Other info ]
  Per the "important notes" section of the borg docs:
  
  https://borgbackup.readthedocs.io/en/stable/changes.html
  
  "Pre-1.1.11 potential index corruption / data loss issue
  A bug was discovered in our hashtable code, see issue #4829. The code is used for the client-side chunks cache and the server-side repo index.
  
  Although borg uses the hashtables very heavily, the index corruption did
  not happen too frequently, because it needed specific conditions to
  happen.
  
  Data loss required even more specific conditions, so it should be rare
  (and also detectable via borg check). [..]"
  
  Theoretically affects all Ubuntu releases before 20.04 (focal.)
  
  I know this is a universe package, but if anyone was up for an SRU that
  would be fantastic..
