When I install a fcitx related package an error show that qtbase-abi-5-5-1 is needed but not installed.

wsx@wsx:~/Downloads$ sudo apt install ./fcitx-frontend-qt5-rstudio_1.0.5-1ubuntu1~qt542_amd64.deb ./libfcitx-qt5-1-rstudio_1.0.5-1ubuntu1~qt542_amd64.deb

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 fcitx-frontend-qt5-rstudio : Depends: qtbase-abi-5-5-1 but it is not installable
E: Unable to correct problems, you have held broken packages.

I tried using command sodu apt install qtbase-abi-5 to find the package but failed. I then download the .deb package from https://ubuntu.pkgs.org/16.04/ubuntu-updates-main-amd64/libqt5core5a_5.5.1+dfsg-16ubuntu7.5_amd64.deb.html but it was not work, the page show that this .deb package provide the qtbase-abi-5 package. Interestingly, I can find few information about this error by google. Some info from Ask ubuntu forum say that it seems the qtbase-abi-5 is not included in libqt5core5a.

I don't know how to fix it. Can you give me some suggestion or some link which do can download qtbase-abi-5 ?

Thanks @GAD3R for your answer, I am sorry that it fails.

Can anyone run following commands successfully?

$ wget http://ikuya.info/tmp/fcitx-qt5-rstudio-qt542.tar.gz $ tar xf fcitx-qt5-rstudio-qt542.tar.gz $ sudo apt install ./fcitx-frontend-qt5-rstudio_1.0.5-1ubuntu1~qt542_amd64.deb ./libfcitx-qt5-1-rstudio_1.0.5-1ubuntu1~qt542_amd64.deb

The package libqt5core5a provide qtbase-abi-5-5-1.

apt-cache search qtbase-abi
libqt5core5a - Qt 5 core module

To install the qtbase-abi-5-5-1 , run the following command :

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt install libqt5core5a

  • @WangShixiang the package `fcitx-frontend-qt5` is available from the Ubuntu repository https://packages.ubuntu.com/artful/fcitx-frontend-qt5 , why you are using a .deb package instead? – GAD3R Feb 05 '18 at 10:15
  • It is not `fcitx-fronted-qt5` package, it is `fcitx-frontend-qt5-rstudio`. I already install `fcitx-fronted-qt5` package on my machine. I want to install this package for fix my problem of inputting Chinese in `Rstudio` software. – Shixiang Wang Feb 06 '18 at 11:46
