Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
Gentoo has discontinued support for ssvnc. We recommend that users |
| 60 |
unmerge ssvnc: |
| 61 |
|
| 62 |
# emerge --unmerge "net-misc/ssvnc" |
| 63 |
|
| 64 |
NOTE: The Gentoo developer(s) maintaining ssvnc have discontinued |
| 65 |
support at this time. It may be possible that a new Gentoo developer |
| 66 |
will update ssvnc at a later date. An alternative may be a manual SSH |
| 67 |
tunnel. |
