I am also seeing the same error. Mint with a DEB install.

[Nokel81]

Seems to be the same issue as #1038 does the workaround there help?

[dawoodmohamed]

@Nokel81 i have tried the solution mentioned#1038 but still i didn't work for me.please help us,all our machine are centos based , and we are completely struck here.

[Nokel81]

@Nachasic any ideas?

[savioteles]

Any ideas? We are facing the same problem here.

[sortel64]

No success building the latest release on CentOS 7 here. We are completely stuck here too. It seems that when Mirantis says Linux they really mean Ubuntu Linux.

Has anyone tried to run this in a Docker container?

[brcros]

Try to add these 2 libs into /opt/Lens :

• libstdc++.so.6
• libc.musl-x86_64.so.1

It works for me, using Lens 5.3.1.
The point is to find the good release. Lens will tell you if the version is not the one...

Bruno

[sortel64]

Thanks for the hint! May I ask where you found these? A particular Linux (e.g. Ubuntu vX, or Fedora X, etc)? Scott

I got the same error on Ubuntu 20.04. It seems that during the installation process the ASAR archive is not unpacked. I had to do it manually and it works!

For DEB install:

npm install -g asar
cd /opt/Lens/resources
npx asar extract app.asar ./unpack
mv app.asar app.asar.orig
mv unpack app.asar

[ymartineau]

here is the workaround I used to install and use k8s lens on centos 7 (and also without account):

$ wget https://api.k8slens.dev/binaries/Lens-5.5.4-latest.20220609.2.x86_64.rpm
$ sudo yum install Lens-5.5.4-latest.20220609.2.x86_64.rpm 

according to https://forums.centos.org/viewtopic.php?t=68062#p285777:

CXXABI_1.3.9 is associated with gcc version 5.1. CentOS 7 has gcc 4.8.5.

install more recent gcc version to get a more recent libstdc++ version.

build gcc (following instructions from https://jdhao.github.io/2017/09/04/install-gcc-newer-version-on-centos/ with the latest current gcc version)

Other dependencies might be required (at least "Development Tools" group, etc.)

$ cd $HOME/programs

(you can use your local mirror https://gcc.gnu.org/mirrors.html)

$ wget https://ftp.lip6.fr/pub/gcc/releases/gcc-12.1.0/gcc-12.1.0.tar.gz

$ yum install gmp-devel mpfr-devel libmpc-devel
$ tar xzf gcc-12.1.0.tar.gz
$ mkdir gcc-12.1.0-build
$ mkdir gcc-12.1.0-local
$ cd gcc-12.1.0-build
$ ../gcc-12.1.0/configure --prefix=$HOME/programs/gcc-12.1.0-local/ --enable-languages=c,c++ --disable-multilib
$ make -j$(nproc) && make install

add symlink to this more recent libstdc++.so library:

$ cd /opt/Lens
$ sudo ln -s $HOME/programs/gcc-12.1.0-local/lib64/libstdc++.so.6

By default lens is asking for an account. https://twitter.com/k8slens/status/1529470612380344321?s=21&t=yvydstNYJkrBPcKI_PTrwQ
To avoid the use of this account and use it locally:

$ sudo vi /etc/hosts

add:

127.0.0.1 app.k8slens.dev

[Nokel81]

We have started building RPM packages on rocky Linux and now have a YUM repo so this should now be resolved.
