Hi, I have the same problem.

I'm using Ubuntu 18.04.

Now I have a partial solution, after install and uninstall several times...

if I click on Calibre nothing hapens, if I write calibre on the terminal nothing happens but...

if i type "sudo calibre" it works...!!!

How can i add sudo permisions to the calibre icon?

Thanks!
Esteban

You don't really want to do that. sudo is all powerful and is intended to keep malicious stuff at bay.
It has been awhile (linux): set the 'x' permission on the icon ( chmod)

Hi,

when trying to start calibre in the shell it gives me the following informations:

Traceback (most recent call last):
File "site.py", line 75, in main
File "site-packages/calibre/__init__.py", line 23, in <module>
File "site-packages/calibre/startup.py", line 204, in <module>
File "site-packages/calibre/utils/icu.py", line 30, in <module>

What does that mean? ;-)

That your distro is really old .

(Specifically, it's shipping with an old version of GCC, which provides the C++ runtimes).

Someone familiar with Mint may be able to tell you if there's a way to coax a more up-to-date version without wreaking too much havoc...

That means it is better reverting to an older version of calibre? I am really sure that everything works fine with the version before 4.2. I will give it a try.

As is noted on the linux download page, you need GLIBC 2.18 or higher
and libstdc++.so.6.0.21 (from gcc 5.4.0) or higher to run calibre. This
is approximately three year old software. If your distro does not
provide it, then you should stick with calibre 3.48 until it does.

Instructions on how to downgrade calibre are on the Linux download page

Ok, problem ist solved. I reverted to the older version 3.48 as shown on the homepage of calibre.

Everything worked fine with every version of calibre and it is working fine now. Thanks a lot for the help to everyone! ;-)

I saw too late that the master is answering... ;-) Thanks for your help Kovid and for this great piece of software I am using for years now without problems.

regards,

Karsten
