Vigrid

Hi Carlos, thanks for your response. Trying the workaround resulted in an error: vigrid@red:~$ sudo apt update [sudo] password for vigrid: Hit:1 http://us.archive.ubuntu.com/ubuntu impish InRelease Hit:2 http://us.archive.ubuntu.com/ubuntu impish-security InRelease Hit:3 http://apt.pop-os.org/proprietary impish InRelease Hit:5 http://us.archive.ubuntu.com/ubuntu impish-updates InRelease Hit:6 http://us.archive.ubuntu.com/ubuntu impish-backports InRelease Hit:7 http://apt.pop-os.org/release impish InRelease Ign:4 https://www.plasticscm.com/plasticrepo/stable/ubuntu ./ InRelease Get:8 http://us.archive.ubuntu.com/ubuntu bionic InRelease [242 kB] Hit:9 https://www.plasticscm.com/plasticrepo/stable/ubuntu ./ Release Err:8 http://us.archive.ubuntu.com/ubuntu bionic InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B4FE6ACC0B21F32 Reading package lists...

N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. So I had to request the public key: vigrid@red:~$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32 Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Thanks a lot!

I have recently installed Pop!_OS Linux (https://pop.system76.com/), which is based on the Ubuntu distribution. I am unable to install the PlasticSCM client using the instruction provided. I have done the preparation steps to add the PlasticSCM repositories into apt, but finalizing the installation results in this: vigrid@red:~$ sudo apt-get install plasticscm-cloud [sudo] password for vigrid: Reading package lists... Done Building dependency tree... Done Reading state information... Done 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: plasticscm-gnome-sharp-mono4 : Depends: libgnome2-0 (>= 2.17.3) but it is not installable Depends: libgnomeui-0 but it is not installable E: Unable to correct problems, you have held broken packages. The libgnome2-0 library has been removed as a part of a general removal of GNOME 2 from Ubuntu distributions newer than 18.04. Is there a workaround for this? Are there plans to support newer Linux/Ubuntu distributions?
