Bug 1471578

is it related with : emails with subject "Caution: Latest nss in updates-testing for F26 breaks DNF." ? 

It depends on the version of nss - not dnf...

nss-3.30.2-1.1.fc26.x86_64 will work.

nss-3.31.0-1.0.fc26.x86_64 will not.

Yes, the problem appears when I pass to nss-3.31.0-1.0.fc26.x86_64.
I haven't received this mail.

Downgrading eclipse-swt to 4.6.3-3 solved it for me, Azureus doesn't work with eclipse-swt 4.7.0-2

Azureus 5.7.5.0-3 built by be in copr [1] works , 5.7.4.0 from fedora repos don't

Sergio, I cannot confirm that 5.7.5.0-3 works. The azureus program appears to start running but there is no window. The following errors are emitted:

$ azureus

Oddly the window finally appeared when I hit Control-C.

Very strange behavior.

I get the same error as the original reporter.

F26, with all updates applied; server edition with KDE installed.

Starting azureus from konsole bombs with the following errors:

azureus-5.7.5.0-3.fc26.noarch.rpm from the copr repository works for me as well, as already mentioned by an earlier reporter.

Created attachment 1313709 [details]
Patch to get azureus to look for the swt.jar and other libraries in the 32bit library directory namely /usr/lib/eclipse

Based on the solution suggested in https://bugzilla.redhat.com/show_bug.cgi?id=1471578 I have modified the f26 azureus binary slightly to make it work.

from my tests 
we may use wayland and SWT_GTK3 
so we need comment out : 

#export GDK_BACKEND=x11
and 
#export SWT_GTK3=0

Also I use in /usr/bin/azureus script :

export CLASSPATH=`build-classpath json_simple bcprov apache-commons-cli apache-commons-lang log4j-1 swt`:/usr/share/azureus/Azureus2.jar

The azureus is using CLASSPATH /usr/lib64/eclipse/swt.jar and the file's real path is /usr/lib/eclipse/swt.jar now.
I just made a symbolic link file /usr/lib64/eclipse/swt.jar -> /usr/lib/eclipse/swt.jar to make azureus working temporarily.

I had built azureus-5.7.5.0-4 in my copr repo [1] and enable SWT_GTK3 and Wayland in /usr/bin/azureus script , may look the commit in github [2]
if you test it , any feedback is welcome , SWT with GTK3 looks good to me , and fedora guides claim that GTK3 is wayland ready .

Got the same problem now and changing the swt.jar path to /usr/lib fixed it for me (F-26 XFCE).

azureus-5.7.6.0-1.fc26 has been pushed to the Fedora 26 stable repository. If problems still persist, please make note of it in this bug report.

I can confirm that this version no longer has that weird bug requiring you to hit Ctrl-C to get the program to start working.
