in /usr/bin/x2gomountdirs line 312 if (system("timeout 30 sshfs $code_conv -o idmap=user,uid=`id -u`,gid=`id -g`,$umaskstr,ServerAliveInterval=300,Cipher=blowfish,IdentityFile=$key,UserKnownHostsFile=$key.ident \"$user\"\@$host:\"@dirs[$i]\" \"$mntpath\" -p $port 1>>$sessiondir/sshfs-mounts.log 2>&1")==0) with a new version of ssh, there is not allowed cipher blowfish so when you use local printing or shared dirs, you can not connect. solution (from upstream?) is to remove Cipher=blowfish parametr.
Thanks for the report! Here is the stable branch upstream commit: http://code.x2go.org/gitweb?p=x2goserver.git;a=blobdiff;f=x2goserver/bin/x2gomountdirs;h=f39d19975c6806ea115921aa0e1949e3dfa44c7d;hp=f0b497edd252481792ebc6e5e73d79158bc4a14c;hb=86a0e421c3da850045459af855a33f646828dd68;hpb=7ae2669b596d3b84f0ba09552d5a8c0e653ce86d I'll test and probably add it to a -r3 version
Done, -r3 should appear on a mirror near you soon: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f08b25af5ac679a57a52ca5a0213deb0800db8c5
