Problem in running uget
Solution 1:
If you still have Segmentation fault (core dumped) message when trying to start uGet, a quick fix is
backup and delete uGet folder in .config/uGet. Then restart uGet
and it will be working again. Most likely issue is with DownloadList.xml (for some reason a error there dump uget core). However by doing so You will lose all your categories, settings and list of downloaded files.
Solution 2:
The problem is you are using the Ubuntu repository...and for some reason Canonical refuses to update the app there.
Ubuntu Software Center has version 1.8.2 which is not even compatible with Ubuntu 12.04 or newer.
The latest version of uGet is 1.10.3 and is available from http://uGetdm.com/downloads
A PPA is also available from that page.
