Upgraded to Ubuntu 17.10 and PixInsight 1.8.5 does not work anymore

[dbrahmbhatt]

Hello all,
I upgraded to Ubuntu 17.10 yesterday (I should have known better, but given that this is a new system and worth an upgrade, I did want to see if everything would work on the GNOME version of Ubuntu). Anyways, long story short, PixInsight does not work anymore. It used to on 17.04. The big change in 17.10 is that it is GNOME based now, however, I would have thought that PixInsight would not have an issue with that, unless some of the PI required underlying libraries have gone missing doing the upgrade.

Anyone else having issues with PI after upgrading to Ubuntu 17.10? I did not see which files/libraries are missing in 17.10, so if anyone knows and can point those out, I will truly appreciate that.

Thanks,
Dhaval

OK. After further digging, found the following in the syslog file of Ubuntu 17.10 -  "/opt/PixInsight/bin/PixInsight: /opt/PixInsight/bin/lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/x86_64-linux-gnu/libpng16.so.16)" and "/PixInsight/bin/PixInsight: error while loading shared libraries: libssl.so.10: cannot open shared object file: No such file or directory".

Any clue will be greatly appreciated. I realize this is not a supported version for PI, but any help in trying to install the missing files will be greatly helpful. My only option at this time seems to be going back to either 17.04 or another distro.

Thanks,
Dhaval

I had the same issue when upgrading from Ubuntu 16.04 to 18.04.

"libz.so.1" is to be found under "/opt/PixInsight/bin/lib"

Now everything is running well (and fast)
