Thanks for update of the img situation. I have then still time to mess this img really bad. I tried to install fmpeg to get youtube-dl to work properly but did not succeed. Again that libc6 - which I tried to install again and it asks me to distupgrade.

I downloaded youtube-dl from upstream and it works fine for me in ED.
I've already had mpv installed in ED, which in Jessie depends on libav.
libav is/was(?) an ffmpeg fork that was used in Jessie, because ffmpeg was a little sleepy at that time.
I have no idea what happens if you try to install actual ffmpeg in Jessie. At least it would collide with libav.

1. As I wrote in one of our PM's, libc6 is set on hold in Jessie for a reason. Don't install any vanilla packages of it without patching them!
I already built the latest glibc packages for Jessie and I'll upload them once I upload a new image.
Besides, there's little point in updating glibc. It doesn't change any functionality and the security point is kind of moot anyway, because even the latest packages are 2 years old by now.

2. If apt asks you to do a dist-upgrade, it means that your installed packages are inconsistent. That may very well be the case, especially if you installed my Midori 7 build, which includes a lot of backports.
Please provide more accurate information! The exact error message and the output of dpkg -l would be useful.

Sorry, did not think to get any answers to my post. Thought it just to be a notion "Dont try this because you break things". Gonna stop this kind of posts in this thread cause you try to really help and answer.

But so you watch in Jessie side with mpv? I download them straight on MyDocs and watch with openplayer on fremantle side.

I didn't try that. Actually, when I saw your post I only downloaded the audio part of a youtube video this morning with youtube-dl and vlc in ED plays it.
mpv technically played it too, but I heard no sound because apparently I have some problem between mpv and pulseaudio, which I'd have to look into.

mpv nowadays has the --ytdl switch, which allows you to play youtube videos via youtube-dl directly, but Jessie's mpv version is too old for that.
I once backported mpv from Stretch to Jessie on amd64 because I needed some newer feature. But that was a nightmare, so I'm not eager to backport mpv on armhf.

And no need. Either someone can fix cutetube2 or one can always download from jessie to fremantle.

Im trying to download something inside Netsurf9 and when click Save in the opening windows asking for location, netsurf crash and close

Could not replicate that problem. Atleast not with downloading an image. Did you install it with the instructions and all dependencies which sulu gave in this thread earlier? Where have you your Easy Debbie (I have on an sdcard)? Where did you install your Netsurf? Have you given enough priviledges to write with your ED (like if it is an sdcard)?

Or have you overclocked your N900? Not really thinking that it could cause it with this actions load but just to gather all possibilities. My phone rebooted when I had it overclocked to 900 and made some apt-get installs. Or have you changed your swap settings? That also caused problems when I had swappolude with recommended settings. Now using only 30 as a swap setting and left other settings to be default and not having swappolude.

I installed this files:

libcurl4_7.64.0-4_armhf.deb
libssl1.1_1.1.1c-1_armhf.deb
netsurf_3.9-1_all.deb
netsurf-common_3.9-1_all.deb
netsurf-gtk_3.9-1_armhf.deb

and libdin2 in adittion to dependency of libcurl4.

No overclocking at moment.

Im trying with image in MyDocs and MicroSD and same result..

Did you start netsurf from chroot terminal or first opening the lxde desktop? And what about rights to write?
